Solid state batteries bring a revolution to the auto and transportation industry.  There is an energy industry consensus that electric vehicles will replace gas powered vehicles in the very near future.  Solid state batteries bring that about rather quickly because they offer increases in energy efficiency,
 
Solid State Batteries replace state-of-the-art lithium-ion batteries used in EVs.  They aim to double and triple energy density.   Another aim is to generate longer range on a single charge and to permit faster charging.  Aggressive promotion of energy efficiency, pursuing sustainable development goals is embraced.  Energy efficiency offers the cheapest, fastest, and cleanest resource for a clean energy transition, addressing the immediate and significant threats posed by climate change.
 
Multiple new technologies are being tried and multiple companies are aggressively investing in the new technology to the tune of billions of dollars.  The stakes are high, there is a transformation away from the internal combustion engine to electric vehicles.
