Researchers propose reason for capacity loss in metal-oxide battery materials

Green Car Congress

The fade in battery capacity is due to the formation and thickening of internal and surface passivation layers during charge and discharge cycles. Magnetite, among other conversion-type electrode materials (i.e., Because the conversion reaction is not fully reversible, these residual products accumulate.

DOE announces $16M for 17 Phase 1 projects in ultra-high temperature materials program; ARPA-E ULTIMATE

Green Car Congress

The total proposed program effort includes development of a coating system consisting of a novel oxidation resistant bond coat compatible with the new Nb-based alloy and a thermal barrier coating for improved durability that can operate at 1700 °C (3092 °F) and a scalable manufacturing process for producing internally cooled gas turbine blades.
