Massachusetts-based SolidEnergy Systems Corp. says it has developed a lithium-metal battery with around twice the energy density of the cells in a Tesla Model S and it needs no thermal management, thus is cheaper. The MIT spinoff says its battery cells demonstrated volumetric energy densities at high as 1,337 Wh/L when tested by another MIT […]

This month, federally sponsored scientists at the Oak Ridge National Lab (ORNL) publicized their creation of an all-solid lithium-sulfur battery with about four-times the energy density of a lithium-ion battery – and this one is being prepared for commercial applications. Stories of close-but-not-quite-ready battery chemistry promising to one day multiply electric car range and vault […]
