Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Nanosheets having asymmetric chemical functionalization on opposite faces are commonly referred to as “Janus” graphene, named after a two-faced ancient Roman god. Sodium is an abundant low-cost metal, and a main ingredient in seawater. We are very happy to present a concept with cost-efficient, abundant and sustainable metals.
