Battery recycling of new energy vehicles is expected to become a new industry

the rapid development of new energy vehicles puts forward new topics for the treatment and utilization of power batteries after their service life expires. According to the five-year service life of power batteries, the first batch of new energy vehicle power batteries will be retired in the second half of 2016. We analyze and predict that the consumption market of new energy vehicles will grow rapidly in the future. As one of the core components of new energy vehicles, power battery technology will continue to make breakthroughs, and the industrial development prospect is unlimited. Recently, shenrenkang, chairman of Zheshang Bank, was optimistic about the development of new energy vehicles, but focused on the comprehensive recycling of batteries

he said that different types of battery products for new energy vehicles are also different. If the battery treatment cannot be planned as soon as possible, it will have a huge impact on the environment and a great waste of resources. Therefore, it is suggested that the battery of new energy vehicles in China must be planned and laid out in advance to avoid the occurrence of resource waste

comprehensive recycling is expected to become a new industry

statistics show that from 2009 to 2015, China has produced 497000 new energy vehicles, especially in the past two years. In 2015, China's production exceeded 350000 vehicles, an increase of 4 times over the previous year, and has replaced the United States as the world's largest new energy vehicle producer and the largest sales market. According to the energy saving and new energy vehicle industry development plan issued by the State Council in 2012, by 2020, the production capacity of pure electric vehicles and electric hybrid electric vehicles in China will reach 2million, and the cumulative production and sales volume will exceed 5million. The rapid development of new energy vehicles has put forward new issues for the treatment and utilization of power batteries after their service life expires. According to the five-year service life of power batteries, the first batch of new energy vehicle power batteries will be retired in the second half of 2016

shenrenkang pointed out that at present, China's automotive power batteries are very different from traditional 3C electronic and electrical batteries. Their characteristics such as large weight and volume, a wide variety of materials, poor consistency of battery cells, prominent safety problems and complex life prediction and evaluation make it difficult to recycle. If it cannot be effectively solved, the contradiction between the development of electric vehicles and environmental resources will be formed. From an international perspective, manufacturers such as Belgium meimeike company and American toxco company are vigorously promoting the research on the recycling of power batteries to provide technical reserves for large-scale commercial recycling. It can be predicted that the comprehensive recycling of power batteries for new energy vehicles will become an indispensable new industry in China

at present, China's recycling of automotive power batteries has not yet formed a complete recycling market due to scale constraints. The earliest domestic enterprises engaged in the resource utilization of waste lithium batteries include Shenzhen green beauty, Foshan Bangpu, Quzhou Sansheng and other companies. However, the recycling of anode graphite, electrolyte and diaphragm needs further technical research, and the relevant departments in China must speed up the research and deployment in this regard

comprehensive utilization is facing the crisis of lack of legal system.

he pointed out that at present, the laws and standards supporting the utilization of plywood for container bottom plate (gb/t 19536 ⑵ 004) for comprehensive recovery of power batteries in China are not perfect. The standard system of vehicle power battery mainly includes disassembly design, appearance identification, packaging and transportation, residual energy detection, cascade utilization, recycling and disassembly, etc. Although China has successively issued regulations such as the technical policy for the prevention and control of hazardous waste pollution and the technical policy for the prevention and control of waste battery pollution, there is no special legislation for the recycling and treatment of vehicle power batteries, and there is a lack of access conditions and management measures for recycling enterprises, which restricts the effective recycling of vehicle power batteries

3. In addition, China's vehicle power battery recycling has not established a national network, an effective recycling model, and the market is not standardized, which is manifested in multiple acquisitions, decentralized operations, and no scale. Batteries are easy to flow into non professional recycling businesses such as private individuals, retailers, auto repair shops and 4S stores. Friendship tips: if there are unclear local institutions, it is easy to cause problems such as resource waste and secondary environmental pollution

the recycling technology is not mature. It is reported that the research on power batteries in China mainly focuses on improving their safety performance and service life, while the research and development of technologies related to recycling are seriously divorced

he pointed out that the five national ministries and commissions recently jointly issued the technical policy for the recycling of electric vehicle power batteries (2015 version), which defined the battery production enterprises and vehicle enterprises (including importers) as well as the cascade utilization of batteries to ensure safety; The enterprise is the recycling entity. However, the majority of consumers are still not aware of the seriousness of the environmental harm caused by waste automotive power batteries. They have not actively participated in the recycling process, and the relevant publicity and education work has not been carried out in depth

speed up the construction of policies, regulations and standards system

in view of the constraints in development, shenrenkang suggested that relevant departments need to speed up the construction of policies, regulations and standards system. He suggested that relevant requirements of the State Council be speeded up, policies and management measures for the recycling of vehicle power batteries be formulated, the access conditions for the recycling industry of vehicle power batteries be studied, and the construction of relevant technical standards system be promoted, Ensure the effective recycling of vehicle power batteries

accelerate the construction of information platform and recycling system, establish a national vehicle power battery management information system, realize the unified supervision of power battery manufacturers, new energy vehicle manufacturers, after-sales maintenance enterprises and recycling enterprises, and lay a data foundation for the next step of building a recycling system

due to the complexity of battery recycling technology, he also suggested that the state should vigorously support the scientific research, technical equipment development, demonstration, promotion and application of new energy vehicle power battery recycling, formulate a list of recommended recycling methods, equipment and processes, and encourage power battery manufacturers, vehicle enterprises and recycling enterprises to jointly establish a technical research working group to promote technological progress. Based on the actual situation in China, select prefecture level cities with good development foundation and relatively mature technical conditions to carry out the demonstration application of vehicle power battery recycling technology and recycling mode, and gradually build a recycling system of waste vehicle power batteries with Chinese characteristics
