UCR researchers find commercial fast-charging damages EV batteries, propose new internal-resistance-based technique

Green Car Congress

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, according to researchers at the University of California, Riverside (UCR) in a new open-access study published in the journal Energy Storage.

Univ. of Missouri team progressing with convection battery; enabling rechargeable lithium-metal batteries

Green Car Congress

Researchers at the University of Missouri led by Prof. The technology allows lithium-metal batteries to be recharged without the dendrite failure (short circuit) that has prevented rechargeable lithium-metal batteries from being commercially viable. Lower mass often translates to lower costs. Source: Dr. Galen Suppes.
