Solid state batteries for
Solid state batteries for buses and delivery vehicles operate at temperatures. This means that they must be plugged in or running. I believe there are a number of companies in this market. Research is being done to make a solid state battery that operates at “room” temperature ranges so they won’t need to be plugged in while not running. . Solid Power might be closer than anyone but they are privately held so information is scarce.. Ford has their fingers in a lot of pies and it wouldn’t surprise me if they pulled a solid state battery out of one of them.
