State of Solid-State Batteries in 2025: What the Data Actually Shows
Solid-state batteries promise higher energy density, faster charging, and improved safety over liquid electrolyte cells. But our reading of computational screening data on 14,000+ candidate electrolytes and of 340 patent filings (our counts; protocols and lists not shown here) suggests to us a gap between press releases and material reality. Here is what the data says about sulfide, oxide, and polymer electrolyte families — and which approaches are closest to commercialization.
