If 2014 is China's new energy car in the first year of China, the 2015 is absolutely new energy car outbreak. According to the Ministry of Industry and Information Technology, in October 2015, my country has produced 50,700 new energy vehicles, an increase of 8 times year-on-year. If the production data of October afterwards, 300,000 new energy vehicles will be exported to the factory in 2015.

As the new energy car guarantees, the recovery problem of the power lithium battery is naturally surfaced. Puzzle 1: This should not be recycled, in November last November, please teach relevant experts, how to see the recycling of power lithium batteries is: Now considering the fashion. According to this expert's point of view, the number of new energy vehicles in the time is not much.

The power lithium battery technology is still immature. The power lithium battery eliminated is basically sent back to research institutions for research, so there is no need to consider large-scale recycling. Today, the single month output of new energy vehicles in October has exceeded half of last year, and with policy benefits and the continuous deepening work of all local promotions, the social security of new energy vehicles will also increase, large number of motivation Lithium battery will face recovery.

According to China Automotive Technology Research Center, by 2020, my country's electric vehicle power battery accumulated draft will reach 120,000 to 170,000 tons. In the recently held "China New Energy Automobile Promotion Application Experience Experience Experience, Wang Bing", the leader of the national 863 energy-saving and new energy vehicle project supervision consulting expert group also said that with the large-scale scrapping of the power battery, battery recycling The reuse work should also be launched and started as soon as possible. It can be seen that the problem of recycling of power lithium batteries has become a problem we have to face.

Puzzle 2: Who is responsible for recycling whether the industry and some of the public's views have tended to be consistent, then the recycling behavior is responsible for September 11th, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly released the power of electric vehicles Battery Recycling Technology Policy "During the comments, it is clear that the automotive manufacturers will become the main body of electric vehicles used. But how much is this implementation, in the production and consumption of new energy vehicle power batteries, will involve battery manufacturers, vehicle companies, and consumers. Battery manufacturers are responsible for producing batteries and related systems, and assembly according to the needs of vehicle enterprises; the vehicle enterprise is responsible for building battery formation to automotive and necessary debugging.

Treatment of waste lithium battery requires discharge, dismantling, pulverization, sorting, housing recovery, acid-base extraction, etc., its professionalism is not existing lithium ion production enterprises and vehicle companies unilaterally achievable. Experts said that in view of the complicated procedures for the recovery process of the power lithium battery, it is best to recover the dedicated battery recovery mechanism.

The expert said that electric vehicles reported that lithium battery recycling and reuse is a new line, whether it is a vehicle-enterprise or battery enterprise involvement, will face many challenges. For battery material manufacturers, due to the similar technical route, the future may occupy the first machine. Puzzle 3: How to recycle although battery manufacturers can occupy a certain advantage in power lithium battery recycling, there have been battery manufacturers and specialized recycling companies to be involved in this business, but because there is currently no relevant experience, the power is lithium Battery recycling is still a "unknown blue sea".

What kind of criteria will follow during the recycling process, and it is still an unknown number. There have been media that there is currently a national standard for new energy vehicle power batteries. The relevant departments have organized new energy automotive enterprises, experts, etc.

to discuss the discussion of 2-3 rounds, discussing the expenses in the process of battery recovery, etc. Battery manufacturer believes that power battery is sold to vehicle companies, and the cost of battery recovery should be responsible by the vehicle enterprise; the vehicle company believes that the battery is used by consumers, and the recovery cost should be borne by the vehicle enterprises and consumers; Consumers believe that the battery purchased by the battery is recycled, and the vehicle and battery manufacturers should make up for this part of the loss. How to balance the equity of the three squares, and the problem that requires the decision-making department carefully considered.

In addition, my country has not introduced the corresponding power battery recycling mechanism. The general method currently adopted is to take the recovery method of nickelicide, nickel-cadmium, and lithium batteries similar to consumer electronics, extracting valuable metals. This form can solve the power battery recovery in the case where the new energy vehicle has fewer amounts, but when the number of scrap dynamic lithium batteries has increased significantly, this method is still discussed.

There have been some views that it will be one of the effective ways to use the energy storage battery will be. Car giant Daimler - Mercedes-Benz recently launched a two-hand battery energy storage device with a capacity of 13 megawatts and a number of companies. In this regard, there are also experts, and different vehicle manufacturers are supplied by different battery manufacturers, while different models of the same vehicle enterprises may also use different models of power batteries, which will cause energy storage batteries in terms of consistency.

question. Therefore, there are insiders that the decision-making department needs to solve the consistency problem of the recycling stage in order to formulate the corresponding unified standards, and use the model because it is still a "blue sea", so what kind of The mode is used for power lithium battery recovery, and major companies are currently in the exploration phase. Daimler - Mercedes-Benz recovers the lithium battery energy storage project or will be put into operation in 2016, although it is only necessary to take only Mercedes-Benz electric vehicles unknown, this may be a car enterprise for powerful lithium battery recycling and reuse One of successful cases.

In addition, there is also a business model of battery production enterprises and professional recycling enterprises to find. If BYD, BYD, BYD, is working with lithium battery recycling enterprises, hoping to achieve a win-win situation in the field of power lithium battery recycling through promotion, operation and operation of energy storage power station and photovoltaic power plant project. There is also a battery production enterprise recycling, such as Watma's safety inspection of the recycled power lithium battery, is built, discharged during the day, and ensuring electricity required during the day plant, reducing the company's electricity Part of cost spending.

In addition, there are also industry insiders that can be applied in electric tricycles, two-wheeled bus, spare power supply, energy storage battery, or metal element, depending on the different circumstances of the scrap dynamic lithium battery. Regardless of the business model, experts recommend not to be too dispersed with the corporate main business business, otherwise it will not be able to obtain higher economic benefits. In addition, to improve the recovery efficiency of the power lithium battery, form an industry, it is necessary to establish a special recycling place, and the recycling location should be far from the city center and should not be too much, avoiding the environmental pollution hidden dangers of the resilience of the lithium battery.

At the same time, it should be re-circulated by the company, and the "disorder" state in the past lead battery recovery link should be avoided, avoiding the old road of lead battery "first pollution,". .
