NEC prototype increase energy density of lithium ion batteries by 30% but has miles yet to go

NEC has announced a planned 30% energy density increase for its future batteries. The Japanese company achieved this by raising the battery’s voltage to 4.5 V (instead of the usual 3.8 V), thereby boosting energy densities to 200 Wh/kg at the cell level. The increase comes from a tweaked formulation...
