Can EV batteries be recycled?

Elsa Olivetti, Jerry McAfee (1940) Professor in Engineering in the Department of Materials Science and Engineering (DMSE) and co-director of the MIT Climate and Sustainability Consortium, says that like all forms of recycling, the EV battery recycling business will be driven by which materials are most profitable to salvage.

Can lithium-ion batteries be recycled?

A review of lithium-ion battery recycling: technologies, sustainability, and open issues. Batteries 10, 38 (2024). Wagner-Wenz, R. et al. Recycling routes of lithium-ion batteries: a critical review of the development status, the process performance, and life-cycle environmental impacts. MRS Energy Sustain. 10, 1–34 (2023).

Can electric car batteries be reused?

It’s possible that many electric car batteries will be reused, not recycled. An older EV battery may no longer be useful for long-distance driving but could still have enough storage capacity to find a second life elsewhere.

Are batteries worth recycling?

Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International license (CC BY-NC-SA 4.0). Many battery materials are valuable enough to repay the intensive work of recycling them—although we should still expect lots of demand for newly-mined nickel, cobalt, lithium and copper.

How are batteries recycled?

In direct recycling, the cathode materials are processed without breaking down their crystal structure. Spent batteries are first manually disassembled and separated into different parts (Fig. 3a), and the cathode materials are subsequently recovered through a relithiation process 92.

Can recycled materials be reintroduced into new batteries?

Recycled materials have traditionally been considered inferior to virgin materials and only applied to low-value applications. If true, this would make them unsuitable for new battery production. In this section, we discuss how recycled materials can be reintroduced into new batteries.
