Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. A rechargeable biomass battery was designed to integrate electricity storage/generation and electrosynthesis of useful chemicals from furfural in one system. Resources Li, J.,

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author. —Prof.
