In recent years, with the government's promotion of the new energy vehicle industry, the production and ownership of new energy vehicles have continued to rise. Consequently, the number of power lithium batteries reaching a peak of 120,000 to 170,000 scrapped batteries is expected to increase around 2020. How to dispose of these scrapped batteries has become a significant issue.
Many industry insiders believe that considering the future development trend of electric vehicles and environmental issues, there will be a blue ocean of potential for the recycling and reuse of power lithium batteries. However, in reality, there are still many problems in the actual operation of power lithium battery recycling, such as a lack of professionalism, poor safety, and non-standard dismantling. The industry urgently needs standardized regulations.
On June 29th, a conference to promote the international standards GB/T33598-2017 "Specifications for Dismantling and Recycling of Power Lithium Batteries for Vehicles" (hereinafter referred to as the "Dismantling Specifications") and "Residual Energy Testing for Recycling of Power Lithium Batteries for Vehicles" (hereinafter referred to as the "Residual Energy Testing") was officially held in Zhangjiagang. It is understood that the "Dismantling Specifications" were published on May 17th and are scheduled to officially come into effect on December 1st, 2017. The "Residual Energy Testing" has been approved and is expected to be officially published and implemented within 2018.
Zhang Tongzhu, Senior Engineer of the Automotive Standardization Institute of my country Automotive Technology Research Center and Head of the Secretariat of the National Automotive Standardization Technical Committee
At the briefing, Zhang Tongzhu, senior engineer of the Automotive Standardization Institute of the my country Automotive Technology Research Center and head of the Secretariat of the National Automotive Standardization Technical Committee, said that the recycling and utilization of power lithium batteries has broad prospects, but China is still in the initial stage. The briefing on this standard will help the healthy development of the industry.
It is understood that the "Disassembly Specification" and "Residual Energy Detection" were proposed by the Ministry of Industry and Information Technology and jointly drafted by Guangdong Bangpu Recycling, CATL, my country Automotive Technology Research Center and other departments and units. They are the first national standards in China related to the recycling and utilization of power lithium batteries.
New energy vehicle power lithium batteries are large and complex in structure. Improper dismantling can easily lead to safety hazards such as electrolyte leakage, short circuits, fires, and even explosions. The "Dismantling Standard" imposes strict requirements on the safety, operating procedures, storage, and management of waste power lithium batteries for recycling and reuse. To a certain extent, it addresses industry-wide development challenges and standardizes the recycling and dismantling of vehicle power lithium batteries in my country, as well as the professional technologies and power lithium battery recycling system.
After prolonged use, used power lithium batteries may experience physical structural loosening and electrolyte leakage, posing safety hazards for their reuse. Therefore, methods for detecting the remaining capacity of used power lithium batteries are crucial for ensuring their safe reuse. The standard "Residual Energy Detection" regulates the testing procedures for power lithium batteries, including visual inspection, polarity detection, voltage determination, charge/discharge current determination, and residual energy testing, providing an evaluation basis for the residual energy detection of automotive power lithium batteries. The implementation of this standard will help improve the safety and scientific rigor of residual energy detection for used power batteries.
Cao Xiong, Head of New Energy Service Department, Guangdong Bangpu Recycling Technology Co., Ltd.
Cao Xiong, head of the New Energy Service Department of Guangdong Bangpu Recycling Technology Co., Ltd., stated that the dismantling of power lithium batteries in my country is still in its initial stage, with immature technology. Standardizing the process as soon as possible will facilitate steady technological innovation and progress. Cao further explained that currently, only a small percentage of power lithium batteries are recycled, the technology is highly complex, and profitability is not yet possible. However, profitability is expected to be achieved within the next two to three years.
The introduction of the "Disassembly Standards" and "Residual Energy Detection" is an important step forward for my country in the recycling of power lithium batteries, but it is still insufficient to regulate the entire market. In order to achieve better recycling and cascade utilization of power lithium batteries, unified standards should be established as soon as possible for the production and recycling processes of power lithium batteries, so as to facilitate disassembly and utilization during the recycling stage and reduce pollution caused during the disassembly process.
Globally, the recycling and reuse of power lithium batteries is still in its infancy. However, due to the rapid development of the new energy vehicle industry, recycling work has reached a critical juncture. Zhang Tongzhu revealed at the event that standards for dismantling, packaging, and transportation of power lithium batteries are being actively developed.
