Higher crystallinity results in better solid-state batteries

Scientists at the Tokyo Institute of Technology have been working on solid-state batteries, which are theoretically safer, more stable, and have higher energy densities than conventional Li-ion batteries with liquid electrolytes. They have recently made progress towards overcoming a major limitation of solid-state batteries: high resistance at the interface between the electrodes and the electrolytes… Read more »

Sepion receives CEC grant for composite battery membranes

The California Energy Commission (CEC) has awarded $450,000 in grant funding to Sepion Technologies, an Emeryville, California company that’s developing a composite battery membrane designed to replace ceramic components. Sepion’s composite membranes  provide high-flux and ion-selective transport, and the company says they can be processed in large-area formats at a fraction of the cost of ceramics. The project’s… Read more »
