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. Researchers have now developed a battery system based on a hybrid cell, which not only stores and provides electricity but also produces valuable chemicals in a flow system.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. With the nanodots in place, the material had a four-fold higher electrical storage capacity than the original MXene and almost reached the theoretical maximum capacity of graphite.
