After the three-dimensional lithium-ion battery is rejected: the data released by the Structured Surplus and Technical Road Dispute Industry and Information Technology shows that in 2015, my country's motivational battery industry has ranked first in the top three in the world. Zhang Xiangmu, Director, Division, Department of Equipment, in January 24, 2016 Forum, 2016 Forum New energy car estimates, my country's powered battery products can meet the production and support requirements of new energy vehicles in the next few years. This number is not completely recognized by the industry.

Fang Jianhua, director of Hefei Xuan Gaoke Power Co., Ltd., General Manager Fang Jianhua believes that since some commercial vehicles have completed 25% of the expected goals, the production estimation of 40 billion woven-time in 2015 is too optimistic.

His prediction is that the sales of power lithium-ion batteries should be maintained at 16 billion watt-hour level. Currently, Samsung, LG, Panasonic and other battery giants have accelerated in my country, and the market competition is intensified. The lower reaches of the battery will encounter cold risks.

According to the battery industry report, my country's battery production will have a total balance in the second half of 2016, but the quality battery production will continue to be tight. This pre-judgment gets the agreement of Fang Jianhua. He believes that the 2016 lithium-ion battery industry will have excessive structural output.

"It can be approved by the vehicle company, and the price is not necessarily enough to meet the market demand, but some batteries that cannot meet market needs may have overproduced production. "The three-dimensional lithium-ion battery is refused to inform, the structure of the battery industry is overproduced into a technical route dispute. Lithium-ion batteries include lithium iron phosphate, three-yuan materials (ie, lithium nickel-manganese acid), lithium carbonate, lithium nickel, and the current state encourages multiple technical routes common development.

But in this way is: Some uncaptified ternary batteries and some stock back to battery, also loading the electric car to run safety hazards. In 2015, many electric buses occurred in my country. One of the reasons is that the number of bus, the number of bus batteries, the chances of accidents have a larger rate.

In this regard, at the 2016 Electric Vehicle Hundred People Forum, the Ministry of Industry and Information Technology clearly stated that the three yuan lithium-ion battery bus is included in the new energy vehicle promotion application recommendation model catalog. This news came out, in the industry, extensive disputes. The reason for the Ministry of Industry and Information Technology is that the three-dimensional lithium ion battery is high, the cycle performance is good, and is an important direction of development of the future lithium-ion battery, but in this field, my country starts late, the safety development and verification of passenger cars is not enough.

The Ministry of Industry and Information Technology is considering further improving new energy automotive product safety technology thresholds, organizing risk assessments for models such as three-yuan lithium-ion batteryb passenger cars in the current safety standard system. Before the evaluation is completed, the three yuan lithium-ion battery passenger cars is included in the new energy vehicle promotion application recommendation model catalog. This statement on the Ministry of Industry and Information Technology, there is industry insiders to understand.

"Since the model development cycle in my country's bus sector is relatively short, it is generally developed for several months, and it is unable to follow the general development process of international automotive industries. At the same time, the relevant standards of electric passenger cars at home and abroad are also relatively improved. In this field, there is indeed an unsafe factor, so it can be seen that the current state is standardizing this industry.

"Recently, Yang Qi, Director of Ningde Times New Energy Technology Co., Ltd. Yang Qi believes that in the next five years, my country's passenger car battery technology trend will turn to Trimetry.

"At present, especially in the field of passenger cars, only the battery energy density can better meet user needs. From the technical itself, if my country's production and use specification is established, the three-yuan materials are higher because of the energy density, from material characteristics, more bright future. However, cobalt belongs to scarce resources, global production is very limited, I am afraid that the second half of this year is insufficient in the early year of the year.

The lithium iron phosphate energy is not so high, but the raw material reserves are rich, and there is a condition for supporting large-scale production of electric vehicles. Therefore, there may be two routes and access space in the future. Wang Bing, director of the Ministry of Science and Technology Electric Automobile Major Project Supervision, believes that electric bus can't use a three-yuan battery, and the key is to improve battery safety standards and control.

"The energy density of the ternary battery is high, and the fast charge can be 30 kilometers, but there are many electric bus passengers. Once the safety accident, the loss will be very large, so the safety of electric bus should be more concerned. "Fang Jianhua believes that suspension does not mean exclusion," This practice is in line with my country's promotion of pure electric vehicles, and the safety performance of lithium iron phosphate can meet the safety requirements of the public domain.

In the passenger car, the three-yuan materials are worth promoting. Therefore, at the same time in lithium iron phosphate, the company should also actively develop a three-dimensional lithium-ion battery. "Secretary of the Party Committee of the Jinlong Automobile Group Co.

, Ltd. believes that the stability of the three-dimensional lithium-ion battery is not as good as the lithium phosphate ion battery, but the safety of the battery cannot be judged by battery material. The safety of the battery is jointly decided by the control system including the packaged system, the quality of production control, etc.

, should pay more attention to the balance of production process. "The logic of our security design and verification is like this, the goal is to be safe. We are most afraid of battery thermal out of control, pressure relief, fire, explosion.

All batteries in a sense are dangerous, but this is also divided by Grade A, class B, and. Especially people, there should be some dangerous goods from Grade A. "Ningde Times New Energy Technology Co.

, Ltd. Chairman Zeng Yun said. Power lithium-ion battery recycling puzzle to be released, and another problem that is currently troubled with dynamic lithium-ion batteries is battery recycling.

There are statistics, 2009-2015, my country has produced 497,000 new energy vehicles, of which 370,000 vehicles were produced in 2015. According to the life life of the power lithium-ion battery, the first batch of new energy automobile power lithium-ion batteries will be retired in the second half of 2016. On January 5, 2016, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Environment, the Ministry of Commerce, the General Administration of Quality Supervision, Quality Supervision, Quality Supervision, AQSIQ, "Electric Automotive Power Battery Recycling Technology Policy (2015 Edition)".

The policy suggests that in order to implement the manufacturer's responsibility extension system, electric vehicle production company (including importers), power battery production company (including importers) and steps use battery production companies to undertake the driving battery recovery and utilization of their own production. Responsibility, scrapped car recycling dismantling company should be responsible for recovering the power battery on scrapped car. However, the technology of recycling batteries is quite complex, such as in processing of used lithium-ion batteries, pretreatment, including discharge, disassembly, pulverization, smelting steps.

It is understood that electric cars in the market in 2011 were not much, and there was not much to operate. Since the early dynamic lithium-ion battery is relatively low, the electric car is driving for a year and a half. "Because of the problem of life problems, there is no tradder utilization, and the recovery of such batteries is more difficult to carry.

Yang Qi's words. "So battery quality is critical. According to the background record, use the electric passenger car in 2011 in 2011, it is expected to operate 8-11 years.

Therefore, 5 years of retired batteries still have residual value. So we won't destroy it into raw material levels, but use the remaining energy for energy storage. However, domestic and foreign energy storage markets have not yet been large, so we will continue to explore this area.

"Yang Qi said. In addition, the development of waste dynamic lithium-ion batteries relates to the development of new energy vehicles, according to battery life, the development of battery recycling companies is lagging behind the battery company 3-5 years. At the same time, the cost of recycling of electric vehicle batteries is high, complicated, and some related companies are not intended to be involved.

Sun Yanxian, general manager of Chaowang Chuangyuan Industrial Co., Ltd., has been said that the powerful lithium-ion battery recovery has a certain difficulty.

The cost of battery recovery is even more costs than sales costs.
