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

With the increase in the new energy car, the recovery problem of the dynamic lithium-ion battery is naturally surfaced. Puzzle 1: Which should not be recycled? The author worked on a new energy automotive industry forum in November last year to see how to look at the recycling of power lithium-ion batteries? The answer is: now considering the fashion. According to the expert's point of view, the number of new energy vehicles in the time is not much.

The dynamic lithium-ion battery technology is not mature. The power lithium-ion 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 the annual output last year (2014 new energy vehicle annual output of 83,900), and with policy advantage and the continuous deepening of all local promotions, new energy vehicles Social security will also increase significantly, large number of power lithium-ion batteries will face recovery issues.

According to my country Automotive Technology Research Center, by 2020, my country's electric vehicle power lithium battery accumulated scrap volume will reach 120,000 to 170,000 tons. In recent successful "my country's new energy vehicle promotion and application related experience exchange and development seminar" The work of battery recovery should also be laid out as soon as possible and start. It can be seen that the problem of recycling of dynamic lithium-ion batteries has become a problem we have to face.

Puzzle 2: Who is responsible for recycling? At present, the industry and some of the public regarding whether the driving lithium-ion battery has tended to be consistent, then who should be responsible for recycling behavior? On September 11, the National Development and Reform Commission and the Ministry of Industry and Information Technology jointly announced that "the relevant electric vehicle power storage battery recycling technology policy (2015 version)" is clear, it is clear that the automotive manufacturer will become the main body of the electric vehicle used power storage battery recycling. But how much is this implementation? In the production and consumption process of new energy vehicle power lithium batteries, it will involve battery production companies, vehicle companies, and consumers. Battery production company is responsible for producing batteries and related systems, and assembling in accordance with the needs of vehicle companies;.

Treatment of waste lithium ion batteries will be discharged, dismantled, pulverized, sorted, hous-recovered, acid-base extraction, etc., its professionalism is not the existing lithium ion production company and vehicle company unilaterally achievable. There have been experts say that in view of the complicated procedures for the dynamic lithium-ion battery recovery process, it is best to recover the dedicated battery recovery mechanism.

The expert said that electric vehicles reported that lithium-ion batteries recycled and reused were a new line, whether it is a vehicle enterprise or battery company, will face many challenges. For battery material production companies, due to the technical route, the future may occupy the first opportunity in the field of scrapped dynamic lithium-ion battery recovery. Puzzle 3: How to reclaim? Although battery production companies can occupy certain advantages in power lithium-ion battery recovery, there is already a battery production company and specialized recycling company to be involved in this business, but because there is currently no relevant experience, it is referred to that the power lithium-ion battery is undoubtedly Still a "unknown blue sea".

How standards will follow during the recovery process, and it is still an unknown number. There have been media that the current renewal of new energy vehicles, experts, etc. are currently organized for new energy vehicles, experts, etc.

, discussions, discussions, etc. Battery production company believes that the power lithium battery is sold to the vehicle company, the cost of battery recovery should be responsible by the vehicle company; the vehicle company believes that the battery is used by consumers, the recovery cost should be borne by the vehicle company and consumers And consumers believe that the batteries they purchase are recycled, and the vehicle and battery manufacturers should make up for this part of the loss. How to balance the rights of the trual party, and the problem that should be carefully considered by decision-making department.

In addition, my country has not introduced the corresponding power lithium battery recycling mechanism. The general method currently adopted is to take the recovery method of nickel-hydrogen, nickel-cadmium, lithium-ion battery similar to consumer electronics, and extract valuable metals. This form can solve dynamic lithium battery recovery problems in the case of new energy car ownership, but if the number of resilient lithium-ion batteries has increased significantly, this method is still discussed.

There have been some views that it will be one of the effective ways to solve the reuse of the resolved dynamic lithium-ion battery. 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. However, there are also experts, and different vehicle manufacturers are supplied by different battery manufacturers, and different models of the same vehicle company may also use different models of power lithium batteries, which will cause energy storage batteries in terms of consistency.

Serious Problem. Therefore, there is an industry insiders that whether the decision-making department should solve the consistency problem of the recycling stage in order to develop corresponding unified standards from the power lithium battery production stage. Puzzle 4: What model is used? Since it is still a "blue sea", what model is used for power lithium-ion battery recovery, and major companies are currently in the exploration stage.

Daimler - Mercedes-Benz recovers the lithium-ion 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 vehicle enterprise for powerful lithium-ion battery recycling One of the successful cases of reuse. In addition, there are also business models of battery production companies and professional recycling companies to find. Such as the reception of BYD in BYD in BYD, working with lithium-ion battery recycling company Greenmei, hoping to achieve a win-win situation in the field of power lithium-ion battery recycling through promotion, operation and operation of energy storage power station and photovoltaic power plant project.

There are also battery production companies to supply internal use, such as Watma to build a recycled dynamic lithium-ion battery after safety testing, build a power storage station, discharge during the day, charging at night, protect the electricity required for the daytime factory, reduce the company's electricity Part of cost spending. In addition, there are also industry insiders that can be applied in electric tricycles, two-wheeled, backup power supply, energy storage battery, or metal element according to different situations of the scrap dynamic lithium-ion battery, and can be used for metal elements, which can also reach the ladder Purpose. Regardless of the business model, experts recommend not to disperse with the company's main business, otherwise it will not be able to obtain higher economic benefits.

In addition, to improve the recovery efficiency of the power lithium-ion battery, form an industry, it is necessary to establish a special recovery location, and the recycling location should be far from the city center and should not be too much to prevent the lithium-ion battery. Environmental pollution. At the same time, the company should be re-circulated by the company, and the "disorder" state in the past battery recovery link is prevented from preventing the battery "first pollution governance".
