Reuse of Power Lithium Batteries: A New Path to Reduce Battery Costs.Moving object detection module

　　The reuse of power lithium-ion batteries refers to the intermediate stage between new energy vehicles and the resource utilization of power lithium-ion batteries. By disassembling, testing, and classifying the power batteries after use, the power battery is reused to achieve a cascade of power batteries, thereby achieving a cost reduction of 30-60% for power batteries. Generally speaking, the standard for scrapping power lithium-ion batteries in new energy vehicles is that the battery capacity is less than 80%. If the remaining capacity is still 70-80%, it is a great waste to directly recycle the batteries. It is particularly important to do a good job in reusing power lithium-ion batteries to reduce battery costs.

　　National policies support the industrialization exploration of the utilization of power lithium batteries. The Energy Saving and New Energy Vehicle Industry Development Plan (2012-2020) issued in July 2012 clearly stated that "we should formulate management measures for power Battery recycling recycling, establish a management system for power battery cascade utilization and recycling, and clarify the responsibilities, rights and obligations of all relevant parties. We should guide power battery manufacturers to strengthen the recycling of waste batteries, and encourage the development of professional Battery recycling recycling enterprises." The country has provided direction for the reuse of power batteries from a planning perspective.

　　The field of reusing lithium-ion batteries for new energy vehicles mainly targets the fields of ICT, households, and renewable energy generation and energy storage. Although the practice of reusing power lithium batteries has not yet been carried out in China, there have been years of demonstration experience in Japan and the United States. Japan and South Korea have been focusing on research on the reuse of power batteries since the beginning of the development of new energy vehicles. These preliminary research works provide a good reference for China to carry out battery reuse research.
