摘要:
The massive production and utilization of lithium-ion batteries (LIBs) has intensified concerns about raw material shortage and end-of-life battery management. The development of effective recycling/reusing strategies, especially for the valuable active positive electrode materials, has attracted much interest from both academia and industry. This study presents a comprehensive patent analysis on the recycling technologies of spent LIBs. We screened and examined 672 patent filings associated with 367 application families, covering the period from 1994 to 2024. The analysis reveals an explosive...
