Solid-state battery tech: What’s close to commercialization, and what’s still years away?
The state of solid-state
Most batteries used in EVs today have a liquid electrolyte, but researchers are seeking solid alternatives for two reasons. One: the liquid electrolytes are flammable, and replacing them would significantly improve battery safety. Two: solid electrolytes could enable much higher energy density with the use of novel anodes.
A lot of confusion arises in the media, because the term solid-state is commonly used to describe both batteries that represent an evolution of some currently available technology (such as using a solid electrolyte with a graphite anode) and the Holy Grail-type batteries that would represent a major leapfrog in performance (such as using a solid electrolyte in a lithium metal battery).
While evolutionary technologies like graphite-anode solid-state are generally approaching commercialization for use in EVs, the Holy Grail-type lithium metal solid-state batteries are still many years away.
