"350-400 Wh/kg energy density. According to Svolt Energy, the pack is the first all-solid-state sulfide battery in the 20 Ah class that will allow electric vehicles equipped with its cells to run 1000km (620+ miles) on a charge. The advantages of a solid-state battery are numerous, but chief among them is the cell's endurance... hot-box test 200 degrees Celsius... hard-to-master sulfide material... patents on both solid electrolyte and diaphragm production, for an all-solid-state battery"
