Russian scientists develop potassium batteries as an alternative to lithium-ion

Thu, 11/14/2019 - 15:10 -- Paul Crompton

Researchers in Russia have developed potassium-based batteries that demonstrate high energy density in fast charge/discharge cycles.

The scientists were looking for a way to avoid dendritic growth by replacing pure alkali metals with their alloys, which become liquid at the battery operating temperature. 

The results of the studies have been published in the Journal of Materials Chemistry A, Journal of Physical Chemistry Letters and Chemical Communications.
