Benefit from the new energy automotive batteries broad space for development

Lithium superior performance, versatile, most promising. Relative to the lead-acid batteries, nickel cadmium batteries, nickel metal hydride battery rechargeable batteries, lithium batteries with high energy density, long cycle life, self-discharge rate is small, no memory effect and highlight the advantages of green. Lithium batteries as the technology advances have been in people's lives in a wide range of applications such as portable electronic products, new energy transport and storage and other fields.

The future of electric cars will drive growth in more than ten times the number of lithium battery materials. It is estimated that a pure electric vehicle requires 40-50 kg of cathode materials and electrolyte, a single mobile phone battery consumption of about a million times. According to our estimates, only required to produce 100 million electric cars lithium-ion battery materials, lithium battery materials will be the world's total demand of the times. Therefore, the promotion of electric vehicles will drive the lithium-ion battery materials show explosive growth in demand.

Status of the global lithium industry: batteries and materials to gain the absolute market share in Japan and South Korea, Japan and South Korea leading enterprise technology. Global Li-ion battery industry is mainly concentrated in Japan, China and South Korea three countries, with China, South Korea Li-ion battery manufacturing technology development and promotion of Japanese lithium battery shipments ratio decreased. China Li-ion battery materials enterprises have developed rapidly, but the overall technical strength, Japan, South Korea's leading enterprises are still in that position, behind China, Japan, about 2-3 years, in large but not strong, with great room for improvement.

Thin-film lithium battery materials and lithium hexafluorophosphate electrolyte technology the highest threshold. Lithium carbonate is the lithium battery materials in the upper reaches of the key raw material, "technology + resources" to build barriers to an oligopoly structure; lithium battery cathode materials: competitive, technological leadership is crucial; lithium battery electrolyte will gradually achieve import substitution, lithium hexafluorophosphate electrolyte maximum Aspect; thin film lithium battery technology extremely difficult, now basically dependent on imports.

Lithium battery materials industry stock picking stock picking strategy. Li-ion battery industry related stocks more, we believe that the company management ability, technology is an industry leader, a certain scale, the future expansion of production capacity or ability to extend the industrial chain will go beyond the industry-related companies, have long-term investment value. We are optimistic about the Foshan Lighting (12.37, -0.73, -5.57%), Fluoride (42.11, -1.99, -4.51%), Jiangsu Guotai (21.66, -1.22, -5.33%), CITIC Guoan (10.40, -0.87, -7.72%) and other related investment opportunities in stocks.

Li: China's auto industry can not be optimistic about new energy technologies take

Li: That is to see how much reserves you have, if you do not have reserves, then that, although not a new thing, a piece of cake, do not you get cut. This concept should not be confused, not a new thing that we are a starting line, this should not be confused. Is not a starting line, everyone should own their own content, needs to do analysis to answer. Compare that with the world what new things that you and that is a starting line.

CRI: Now the Chinese government a great investment, policy support in the international support is great.

Li: The good, the Chinese government's investment in electric vehicles is very large, and very seriously, this is really good. New energy vehicles or electric vehicles, electric vehicle technology we call, it really is the future direction of development. Because it can not solve China's pollution problem in the local, even if the electricity is coal sent, not to say that low-carbon economy, but after all it is local, it can solve the pollution problem, you can solve the energy transport. China's strengths can also be used, for example, many of our coal, natural gas, and this is indeed a strategic move. But the future is not very large as an industrial leap, this also depends on our own for the automotive industry technical level of certainty.

CRI: You think the technology now to grasp the extent of how well?

Li: not optimistic.

CRI: General Lee, you just said is not optimistic, you see some problem?

Li: We have to do the foundation, we have to do technology.

CRI: now all the technical brands say they have this foundation.

Li: The key problem is that we are not really grasp like batteries, motor core technology. I just see Guo right or good. We really do the core, not to say that do cross.

CRI: just academician Guo Konghui interview, he mentioned a very advanced one point, he said China is mainly low-speed development, now relatively small size, in Shandong, Henan, a large number of running that. Do you think this line you agree?

Li: We have just finished and the Ministry of Information Industry recently conducted a survey on low-speed change of car.

CRI: You think?

Li: not to say a direction.

CRI: Why?

Jun: Why develop this thing, so a lot of development, he talked about how impressive advances across, this is a problem.

Tencent car: we did not participate in the FAW have new energy battery standards, what is your opinion on the standard battery it?

Li: In our batteries, but most of our strengths, we have mastered the technology of lithium iron phosphate should give full play to their strengths in the early, but we should fully recognize that this is not a pursuit, not the future. Lithium iron phosphate is definitely not.

CRI: So what is?

Li: What is the ah, you go to research studies, I would like to get an answer.

CRI: Now the third generation of battery in the study, right?

Li: the world has such a view, inter-cell to move forward three steps, now six dollars to eight dollars by the year 2000 can cross-step, to half the price. 2025 or 2030 to achieve two dollars per yard, the cost down a lot. But take a look at what materials to achieve such a leap, if you do not achieve this leap, the electric car is the government can not afford to fill.

CRI: Do you think electric cars are the new energy trend?

Li: It should be said, in my opinion technology is balanced, not to say unique. You see now what the world, how can this technology only. European diesel done a good job to do, the Japanese have done well.

CRI: But now China in the new energy policy orientation.

Li: If the Government has a tendency, then this is right. Key to business, business to have their own strategic planning, in fact, electric or at any Ye Hao, mainly carbon dioxide, we should engage in low-carbon. If can get a data, for example, in a B-class car, 1500 km section of 40% of fuel-efficient cars, then if it turned out to be a hundred km 11 liters of fuel, saving 40%, then it is down to section 5 liters, equivalent to savings of 5 liters is not leased this car is pure electric, there is nothing wrong with it.

CRI: Mr. Wu made a statement just released six years before the new energy vehicles FAW is it? This plan is what?

Li: You have to ask tread.

CRI: The new energy plan look like?

Li: This you have to ask him.

Breakthrough in battery technology is difficult obstacle to the development of smart phones

Competition in the smart phone market is increasingly fierce. As previously reported we have a growing number of smart phone operating system in the efforts to expand its market share, while the manufacturers are also working to improve their market share in smart phones. More and more smart phones available, they are more powerful, more and more high configuration, all display the smart phone market is growing rapidly.

However, the development of smart phones is not a smooth sailing. Despite the rapid development of technology, more and more new technology into the mobile space has been greatly improved user experience, but there are still some bottlenecks restricting the development of mobile phone technology. Battery technology is one of the most important aspects.

Compared to ordinary cell phones, smart phones tend to have higher than normal cell phone hardware configuration, but with more features smart phones have a greater frequency of use. This means that the smart phone's power consumption is correspondingly greater. With the large size of the touch screen into the mainstream, more and more Internet-based applications, smart phone also continues to increase the power consumption trends.

Inconsistent with this development, the mobile phone's battery technology has not made any major breakthrough. The current battery capacity and smart phones a few years ago, to enhance the range is limited, its very difficult life satisfaction of users. As far as I know, a lot of smart phone users are required to charge the battery every day.

Nokia Research Center Henry Tirri said in a recent interview, go through a few years, breakthroughs in related technologies, the smart phone's battery life is possible to achieve "good" level. Henry Tirri that the smart phone battery "good" level is a charge to use about a week, but now many high-end large-screen smartphone was less than eight hours of continuous use.

Short term cell phone battery technology, there is no breakthrough

Defects in battery technology for operators and manufacturers have an effect. Users may hesitate whether to buy a standby time is very short, smart phone, but it also limits the use of smart phone users to make more Internet applications.

Henry Tirri said that as the phone's basic function is to voice and information, so on the phone before the power management of the study was to optimize for both. But in the past two years, with the rapid development of mobile phone technology, there has been a faster processor and more power bigger and brighter screen, and with the "cloud" concept generation, a large number of applications require connected to the Internet server, which also takes a lot of power, however, did not keep up with the battery of this trend.

And taking into account the limited volume of safety factors, the current lithium batteries used in mobile phones is difficult to have much to enhance the capacity, mobile phone manufacturers and battery manufacturers are working on new battery technologies, including the use of solar energy, kinetic energy and so on. However, at present these technologies have no real breakthrough is not yet widely used. ABI Research analyst Michael Morgan said the smart phone battery to get involved in a lot of breakthroughs in technology, but these technologies are related, each technology must wait for other related technology.

Therefore, in the enjoyment of smart phones faster, more feature-rich at the same time, within a period of time, smart phone users still have to endure the pains of the battery can not be sustained. And if this situation would not improve as quickly as possible, perhaps even the development of the smart phone industry a huge impact.

Hybrid Fuel Cell Bus Development B

1.2 the direction of hybrid buses in the city bus

China to build environment-friendly, resource-saving society, and "Eleventh Five-Year Plan" proposed 20% target of energy saving, development of enterprises in urban public transport is to achieve hybrid urban bus emission reduction is one important way. Large urban public transport is oil, oil consumption is about 30% of the total cost, energy saving is important, and this city bus is also a must to achieve the goal. China's urban public traffic congestion, urban public transport in our typical operating conditions, the average speed is only 10 ~ 20 km / h; engine idling time as much as 29% of the total operating time; braking 24% of total time. This makes the most of our long-term urban bus high energy consumption and emissions in the high negative working condition. The hybrid city bus through the motor to improve engine operating conditions, to work in areas of low fuel consumption and low emissions, so easy to achieve the effect of energy saving and can provide better acceleration performance. Also city bus space, carrying capacity, low speed, driving range is 300 ~ 350km, on the hybrid power system size and weight requirements much lower than the sedan and other models. Therefore, compared with other types of vehicles on the most suitable for hybrid bus system. In addition, because the bus company car volume, easier to organize large-scale commercial fleet operations.

1.3 hybrid electric bus development at home and abroad

World countries are actively promoting the development of hybrid electric transit bus and operations. New York in 1998 to provide the first batch of 10 BAE-Ori-on series hybrid electric transit bus demonstration operations, there are currently over 500 such buses in New York, Toronto and San Francisco and other urban applications. GM in Seattle, launched the first GMAllison parallel hybrid transit bus operated. Currently, more than 400 vehicles, including Houston, New York, Los Angeles, and Seattle running more than 28 North American cities this year, the company has received more than 1,500 cities in the United States sets the order. In Japan, Toyota, Honda and other auto giants have invested huge human and financial resources to develop hybrid bus, and has launched several models.

China attaches great importance to the current hybrid research and development, held in 863 countries, meeting on electric vehicles, hybrid vehicles in China research and development of electric vehicles, was identified as a priority the development of object. The General Assembly adopted the "Long-term Scientific and Technological Development Plan (2006 ~ 2020)," clearly the new energy vehicles as one of 68 priority themes. In 2006 the Ministry of Construction has developed the "energy saving environmentally friendly city bus" project included the Ministry of Construction in 2006 to promote science and technology projects, and projects, including the development of a hybrid city bus is the main content. And in early 2006, commissioned by the Ministry of Construction Science and Technology Committee and the Committee of Experts on city vehicles Transport Group Co., Ltd. Shanghai Volkswagen jointly organized the "hybrid electric city bus," the preparation of industry standards, March 21, 2007 prepared by the "hybrid electric city Bus "industry standard hosted by the Ministry of Construction will be the industry standard for review. The meeting also decided to Foton, Xiamen Golden Dragon, Anhui Ankai 3 of 3 companies to develop hybrid city bus prototype by the Shanghai Dazhong Transportation Group Co., Ltd. trial. And in March 2007, the Ministry of Construction of the CST by the Committee of Experts on city vehicles and the Society of Automotive Engineers of China branch of electric car jointly host the "application of hybrid electric city bus Seminar", on hybrid electric city bus in the development and application encountered in the discuss a wide range of issues to further promote China's hybrid electric city bus development.

Molecular wire brush technology to promote bio-fuel cell development in vivo

Recently published "chemical communication" magazine published an article that researchers at the University of Georgia has developed a guide wire brush techniques of molecular charge, which made the development of microbial fuel cells in vivo the first step. Vivo biological fuel cells for cardiac pacemakers, cochlear implants and prosthetic devices such as implantable power supply. "Chemical Science" magazine said, "This is a major breakthrough in nanotechnology."

Jason Locklin chemist from the University of Georgia research team led by molecular chain and benzene thiophene chain sprayed on metal surface to form a thickness of only 5 nm to 50 nm ultra-thin films. The film's structure is like a toothbrush, while the conjugated polymer chains like bristles. The researchers said such coatings for polymer brushes. Molecular wires is actually very close in this film polymer chain. Extended in order to remain in the molecular chain tightly, they used a feature called "transplantation" method, the first spraying a thin layer of thiophene as the first coating, and then use technology to build a control polymer chain thiophene or benzene chain.

Locklin that the use of the body of fuel resources (such as glucose) is very difficult. Although the enzymes in the human body has a good conversion of chemical energy into electrical energy capacity, but they have played a role in the insulating layer of natural protection to prevent the transfer of electrons from the active site to the electrode, so not very useful. The molecular wire is able to provide a better channel the flow of electricity charge. Transform the performance of organic semiconductors and size depends on the number of units. Thiophene itself is an insulator, but in a controlled manner a number of thiophene molecules linked together to make this polymer with a conductive properties.

Locklin stressed that the technology allows scientists to control the various polymer structure, so as to expand such as sensors, electronic devices such as transistors and diodes, the diversity of uses possible. The next step is to develop related applications. For example, the polymer brush can be used in a range of technology and human activity in organizations closely connected device, such as biological sensors, artificial limbs, pacemakers and bionic ears. At the same time, this thin film transistor itself may also be used as solar cells or photovoltaic devices being this.
