Moderator: Let’s now look at the electric car technology is more advanced lithium-driven, including before, Tesla will do some sports car, is to use lithium batteries, although to achieve a long life time. It may only be lithium batteries, but also more than 1,800 lithium core. Do you think electric cars lithium battery will be a major technical means?
Schkade: as I am not a battery or a lithium-ion battery experts. So, now I can not say lithium-ion battery is not the best solution, is not the most should be used in our new energy automotive industry as a way of them. But I know that most of the advanced battery technology is still on the lithium-ion batteries. Many of the companies the possibility of future battery development and R & D efforts are now concentrated in the lithium battery research. But lithium is not a simple one, as you just said 1800 core that, in fact, many, many lithium batteries for various automotive products. In the lithium battery, there is a nickel-hydrogen batteries, lithium batteries may not be as advanced technology. Now why there are different battery technology? Because some areas are not rich lithium resources, how to do that lithium batteries? Lithium is not a rich resource for the area concerned, to mass production of lithium as fuel for another decade or two decades, this is a problem we need to face. In the end, the problem is the development of lithium batteries are lithium-ion battery technology itself, or because we are not lithium resources, it is not clear. I think that is a double problem, first because the need to develop lithium-ion battery technology, and the second is now available lithium resources, we can not, we do not have enough battery raw materials. This is a further problem, we take a look at over time, lithium-ion batteries will become a leading, in the future be able to solve a wide range of battery solutions for various problems.
Yu Hongtao: Judging from the periodic table inside, or the most advanced lithium-ion battery technology a. But tell the truth, the current lithium-ion the hands of human technology in order to truly achieve large-scale commercialization of electric vehicles still have some distance. Therefore, in our industry are scientists, including some of the new technology is more than this generation of lithium-ion battery technology more advanced technology to do some new energy vehicles energy, such as reported in the previous paragraph I see a number of cars in the study Lithium-air battery, once it can form after the industrialization of its energy density is almost comparable with petrol.
Moderator: Now many companies are developing electric cars including the use of lithium batteries, but take into account the life cycle of the battery in the future after the end of the degradation of its pollution of the environment is greater than the existing internal combustion engine?
The Tao: This is a very important issue, it relates to the future, the lithium-ion battery industry. Realistically speaking, at present the whole industry, including government research on lithium-ion battery more effort is placed on how to improve the performance of lithium ion, and how to recover, if the guarantee lithium-ion batteries for future use is over does not affect the environment, this area is relatively less studied.
Schkade: lithium-ion battery technology is just starting, right after its environmental impact, which I personally do not clear, I am not a battery technology experts. I think the battery degradation, recycling, the environmental impact of this point, it needs further consideration, to be seen. Now its impact on the environment, pollution how, there is no definite answer. I think even the battery expert in now or ask a number of technical experts, he has only to give some of his personal views. After the concrete reality of pollution for what he could do nothing to give you a very accurate answer. SAE speaking to us, our job is to convene the world’s experts in automotive technology, come together to discuss means of finding solutions to car problems. In Shanghai in October this year, our Center for Automotive Research SAE and electric vehicle battery joint summit forum, it is certain that a considerable part of the discussion focused on the environmental impact of batteries and recycling issues, to the time that many experts to discuss this. If we are very concerned about this issue, then, to join or pay attention to our SAE battery summit will be a very good option.
Moderator: SAE or on the Center for Automotive Research in China, is considered such a program is responsible for selling off the train car, the battery provided by other manufacturers. To enter the charging station when it can not replace the battery charge, such a program?
Schkade: automobile production cars, batteries for recycling is a very good solution, which is now in the end is the best way, is hard to say. The way you just mentioned is a method, we have other ways to solve this problem, for example, this battery in your car outside, consumers rent the battery is also an option. Because in terms of electric vehicles, more central part of the battery if you want to dispense with the need to meet a lot of cars on the battery requirements, including the acceleration, the exercise of cars, the car’s performance on the battery requirements. If the battery after a period of time no longer fit to drive, you can use this battery to the other. Such as the electric field of the stored energy, or some other industries which can be used. I say this example is not to say the future will do, but would like to assure you that such a model, the market if they have such an opportunity, entrepreneurs may find the opportunity of a new industry emerged. Through the success of these methods to find a suitable business model, the battery problem will be solved. It does need a lot of work. This is my personal view, this is a very exciting for us commercially.
Yu Hongtao: charging now there are many global practice, including fast charging and battery replacement. Battery replacement in this manner have a larger problem that the size and the size of the battery there is no way unified. For example, the bus probably easier to unity, because it put the battery in the space more rules, but also relatively large, can put the battery the battery design of its space. For the average passenger car in terms of different cars put the battery space, shape, size is not the same. Therefore, this replacement battery in a different car when very difficult to achieve, which is affecting the battery replaced a bottleneck in this way.
