Graphene 3D Lab showing prototype 3D printed battery; potential for structural batteries

Green Car Congress

which develops, manufactures, and markets proprietary graphene-based nanocomposite materials for various types of 3D printing, including fused filament fabrication, has developed a 3D printable graphene battery. However, a true multi-material 3D printer would enable the printing of the entire battery in one single print, the company notes.

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.
