Lithium extraction, specifically, poses challenges due to its reliance on vast amounts of water, impacting local communities and ecosystems. Because of this, several companies are exploring sustainable mining practices and alternative sources of lithium to mitigate impact. Furthermore, the ethical implications surrounding cobalt sourcing, given its association with exploitative labor practices, have spurred research into cobalt-free battery technologies as a formidable solution.

Additionally, the end-of-life management of batteries is an area warranting attention. As we transition to a high-capacity battery market, managing discarded batteries responsibly is critical. Effective recycling advancements can minimize waste, recover valuable materials, and reduce the necessity for new mining operations. Thus, pursuing environmentally friendly technologies goes hand in hand with advances in electricity storage, creating a feedback loop of innovation geared toward sustainability.
