ARPA-E awards $42M to 12 projects for advanced EV batteries; EVs4ALL program

Green Car Congress

The US Department of Energy (DOE) will award $42 million to 12 projects to strengthen the domestic supply chain for advanced batteries that power electric vehicles (EVs). Combining the TMCT with a high ion conducting solid-state electrolyte will enable rapid charging at ambient conditions. Award amount: $3,198,085).

U Maryland team devises new method to stabilize high-capacity Si anodes for Li-ion batteries: interfacial oxygen

Green Car Congress

Interfacial oxygen between the silicon and carbon improves electrode performance. Researchers at the University of Maryland have improved the cycle life of silicon/carbon matrix-composite electrodes by 300%, even at mass loadings, solely by the chemical tailoring of the interface between the silicon and the carbon with atomic oxygen.
