Improving the end-of-life management of electric vehicle batteries.

SB 5586 requires electric vehicle (EV) battery producers to manage end-of-life batteries, directly affecting manufacturers and battery sellers in Washington. Key provisions include: mandating permanent labeling on new EV batteries by 2028, banning solid waste facilities from accepting EV batteries after 2029 (unless authorized), and requiring producers to submit approved battery management plans by 2028. These plans must cover collection, recycling, reuse, or repurposing of used batteries through environmentally sound practices. The law aims to ensure responsible disposal and recovery of valuable battery materials like lithium and cobalt, aligning with similar efforts in California and New Jersey.
