What Are The Difficulties Encountered In China's Power Battery Recycling? How To Promote The Development Of Power Battery Recycling Industry?

- Dec 25, 2019-

According to statistics from the China Automobile Association, from January to April 2019, the production and sales of new energy vehicles in China reached 360,800 and 360,000, respectively, an increase of 58.5% and 59.8% year-on-year. With the rapid growth of new energy vehicle production and sales, how to follow up the recovery of power batteries and how to effectively dispose of retired batteries have gradually become the focus of the industry.

Chen Qingtai, chairman of the China Electric Vehicles Hundred People Association, said that by 2030, China's electric vehicle ownership will reach 80 million. As the production and sales of new energy vehicles continue to rise, the issue of power battery recycling will also pose new challenges in the near future. If the problem of power battery recycling cannot be properly handled, the new energy industry chain will not be truly green. Closed loop, the future is also likely to form backlashes on the environment and economy.

China's power battery recycling industry is currently in its infancy, and it continues to explore and grow in many aspects such as recycling models, system construction, market supervision, and commercialization models. In order to better promote the construction of the power battery recycling system, we may try to find ways to crack it from the following aspects:

First, the battery design concerns recycling needs. In terms of power battery recycling, in addition to optimizing post-processing solutions, we should also consider the need for recycling at the beginning of battery design. Such as a simple battery structure design, it is more convenient to improve the efficiency of recycling and increase the degree of automation in the recovery process of power batteries. The introduction ensures that the source of the whole life cycle of the power battery can be traced, traced, the nodes can be controlled, and the responsibilities can be investigated.

Second, reasonably priced retired batteries. At present, the pricing mechanism of decommissioned batteries in China is not perfect, and the battery capacity and quality testing of decommissioned batteries have not formed a uniform standard, so it is difficult to form standardized pricing principles. In the process of recycling retired batteries, there are also problems such as excessive recycling costs and insufficient profit margins. Therefore, it is urgent and necessary to establish a complete pricing mechanism for retired batteries.

Third, increase research and development of key technologies. In the process of testing, recombining, disassembling, recycling, etc. of retired batteries, compared with developed countries such as Germany, China's current technological maturity and degree of mechanical automation need to be improved. On the premise of ensuring safety and environmental protection, China's power battery recycling technology field should also continue to increase research and development efforts to improve the efficiency of power battery recycling, improve the intelligence and automation of production lines, and indirectly improve the economics of power battery recycling.

4. Establish an evaluation standard suitable for the application scenario. Before the retired battery is used for the first time, it must first be tested and evaluated by a professional organization to determine whether the battery capacity and various performances can meet the requirements for the first time use. Taking into account the different application scenarios, the requirements for the use of the battery in different steps are not the same. With the continuous enrichment of China's step use scenarios in the future, it is necessary to establish evaluation standards that meet the application scenarios.

Fifth, do a good job of top-level construction. In order to further accelerate the transformation and upgrading of the automotive industry and achieve sustainable development of the new energy vehicle industry as soon as possible, it is necessary for China to strategically lay out a power battery recycling system to ensure the safe and effective recycling of large-scale power batteries in the future. To this end, the state needs to provide guidance for the recycling of power batteries, clarify the development direction of the industry, rely on the inter-ministerial joint meeting system for energy conservation and new energy vehicle industry development, and strengthen supervision and guidance of local governments, enterprises and related institutions. At the same time, diversified incentives should be launched to actively explore sustainable business models.

Sixth, improve recycling management practices. The recycling system involves many links, and sound management standards, related standards, and increased barriers to entry will help push China's power battery recycling system toward a standardized direction. At the same time, the formulation of standards for the classification, packaging, transportation, storage, step utilization, and dismantling of scrap batteries during the recovery of power batteries is also conducive to further strengthening safety management.
