UK startup claims its electrolytes can triple flow battery energy density

A startup led by Cambridge University scientists and the former chair of Oxford PV is attempting to commercialize flow battery electrolytes with greater energy density than vanadium-based batteries. Kodiaq Technologies claims its electrolytes can be deployed as a drop-in solution for redox flow batteries.

From ESS News

Kodiaq Technologies is developing organic electrolytes for redox flow batteries that it claims could achieve 300% the energy density of vanadium-based alternatives.

The UK-based startup has developed an organic electrolyte that is currently able to store energy at up to 50 Wh per liter – exceeding typical vanadium-based electrolyte energy density – and has identified a development pathway to further increase energy density.

Unlike a lithium-ion battery, redox flow batteries store charge in a liquid electrolyte which is separated by a membrane.
