Establishment of a battery traceability mechanism

Sales of new-energy vehicles in January and February were nearly 75000, up 200 % from a year earlier, according to data released by the China auto industry association. The new energy car industry has entered the golden development period. At present, the total target sales of mainstream car companies have exceeded 700,000 vehicles, which is close to the total amount of new energy sales in China. However, with the first batch of new energy vehicles on the road five years ago, China has also ushered in the "small peak" of power battery decommissioning, and its recycling and reuse have become a thorny problem faced by the new energy automotive industry.

It is reported that since 2010, China has started to pilot subsidies for new energy vehicles, and in 2016 it will comprehensively promote new energy vehicles. The general power battery will be retired after 5 to 6 years. This means that from 2018, we will have a large number of power cells into the end of life. According to projections, by 2020, the total number of batteries scrapped in China will reach 120,000 to 170,000 tons. "Compared with lead-acid batteries in the past, copper, cobalt, lithium and other metals in lithium batteries that are commonly used today have higher economic value. Under the regulation of market mechanism, used power batteries will be favored by recycling enterprises. "A technician of a new energy car company said. The industry believes that the retired new energy car battery itself still has value, and its recycling and utilization methods are mainly cascade utilization and resource recycling.

However, at present, the overall recycling network system of power batteries is still very imperfect. Whether it is the use of echelons or recycling, it has not really formed a scale, and the technology still needs to be upgraded. It is understood that only a few third-party recycling enterprises in China have built their own recycling networks, and the power battery recycling system for motor enterprises, battery enterprises, recycling enterprises, and logistics enterprises is far from being established.

"The key technologies for power battery decommissioning and recycling are not yet mature enough. Some battery recycling companies still use manual dismantling or traditional recycling processes. Zhangchangling, a senior engineer at the China Automotive Technology Research Center, said the traditional process of recycling 1 ton of used lithium iron phosphate power cells is not only not profitable, but it could also be a loss. At the end of February this year, the Ministry of Industry and Information Technology and other seven ministries and commissions jointly formulated the Interim Measures for the Recovery and Utilization of New Energy Vehicle power battery Management, which clearly defines the main responsibility of automobile manufacturers for power battery recovery.

However, some details still plague companies, and industry insiders call for more detailed standards. Some experts said that the urgent task is to solve the problem of battery traceability as soon as possible and use the new energy vehicle supervision platform to establish a battery traceability mechanism so that the entire process of batteries from "life" to "death" can be traced back. At the same time, it supports enterprises with research and development and refining capabilities, especially guiding the integration and development of echelon utilization enterprises and battery enterprises, and guiding the integration and development of recycling enterprises and resource materials enterprises.
