Will power lithium battery recycling demand increase?

The recycling of power lithium batteries can not only protect the environment, but also due to the scarcity of resources, the recycling of battery materials has a positive impact on the sustainable development of electric vehicles. Taking cobalt resources as an example, according to statistics from the Qinghai Salt Lake Institute of the Chinese Academy of Sciences, the current global cobalt production is 150,000 tons, of which 80% comes from the recycling of waste materials. Currently, 95% of my country's cobalt resources rely on imports, and cobalt for batteries has accounted for 69%. In order to standardize the recycling of power lithium-ion batteries, relevant policies have been intensively introduced since last year, but the actual results have been minimal, and the recovery of power lithium batteries has risen slowly. The data shows that in 2015, the total number of scrapped power lithium batteries was 20,000 to 40,000 tons, but the corresponding battery recovery rate was only 2%; in 2016, the power lithium-ion battery actually went into dismantling and recycling less than 10,000 tons, more than 80% Scrap batteries are still stranded at car companies. In the author's opinion, there are three important reasons for this problem. First of all, the recovery of power lithium batteries is difficult. As a part of the car, power lithium batteries have been transferred to consumers with the sale of cars. Consumers have the right to dispose of them. It is difficult to control whether they can flow into formal channels. For example, many scrapped power lithium-ion batteries flow into private individuals. workshop. Second, the scale of power lithium battery recycling is insufficient, and the company's enthusiasm is not high. Beginning in 2015, the new energy vehicle market has only begun to explode. Whether it is new energy vehicles or power lithium-ion batteries, they have not yet entered the stage of large-scale scrapping, so related companies have insufficient recovery power. Third, the economic benefits of battery recycling and dismantling are insufficient, the overall investment far exceeds the value of recycling, and dismantling is more dangerous. The sources of decommissioned batteries are complex, and the disassembly processes are different, including the differences in the manufacturing and design processes of different types of batteries, the form of series and parallel groups, the battery life, the variety of models used and the diversity of operating conditions, etc. Different requirements lead to higher dismantling costs. Therefore, the author proposes that, first of all, it is necessary to increase the enthusiasm of consumers to participate. For example, the method of collecting a deposit can be adopted, and the battery deposit is included in the price of the consumer buying an electric car. When the consumer returns the used battery, the deposit can be refunded. Second, we must increase the company's enthusiasm for participation and encourage the development of dismantling and recycling companies. For example, environmental governance tax is imposed on battery processing companies or tax reduction or exemption for waste battery solution companies. Although the current number of discarded batteries is relatively small, the initial investment is large. The state can adopt appropriate policies to support the development of battery recycling companies. Third, speed up the standardization of power lithium batteries. There are many types of lithium batteries in China. The battery structure is complex and there is no uniform standard. If retired batteries are to be used in cascades, they must be disassembled, sorted and regrouped. The process is complicated, and the recycled batteries come from different manufacturers, with different specifications. not exactly. This means that a variety of different design methods may be required for battery packs, which will increase the cost of secondary pack design and production costs, resulting in complex disassembly and recycling processes, and it is difficult to form industrialized operations. Fourth, set corresponding indicators for battery recycling, and set penalties for companies that do not meet the standards. Clear rewards and punishments will help to urge related companies to complete recycling tasks and improve the recycling rate of batteries.
