In Lithium’s Long Shadow: Other Battery Tech Is Still Key

By Josie Garthwaite on September 11, 2009

Lithium, the key mineral for lithium-ion batteries used in many consumer electronics, computers and upcoming electric vehicles, is a limited resource residing in large quantities below Bolivia’s salt flats (among other places). That fact has helped create buzz about the chemistry, electrifying it with political controversy and fears about “peak lithium” (see our take on the looming lithium squeeze here). But while lithium-ion has seized the limelight of late, it’s only one of several battery chemistries that will have key roles to play in the transition to a cleaner transportation system and power grid.
