North American Energy News [theamericanenergynews.com] reports today on a breakthrough in battery technology that could dramatically improve electric vehicle performance.

Thirty-seven years after co-inventing the technical breakthrough that made lithium-ion batteries commercially viable, 94-year old engineering professor John Goodenough has developed a solid-state battery he thinks will solve the high cost and low range holding back EV adoption.

The solid-state batteries have three times the energy density (the measure of how much electricity can be stored in the battery) of conventional Li-ion EV batteries, but experts suggest it could be another fifteen years before they're commercially viable.
