Will the global number of publicly disclosed patents related to solid-state battery technology exceed 25,000 before the end of 2027?

Solid-State Battery IP: Global Patents Pass 25,000 by 2027

Solid-state batteries (SSBs) promise higher energy density, faster charging, and greater safety compared to current lithium-ion technology, making them essential for the next generation of EVs and consumer electronics. This prediction is that the cumulative global number of publicly disclosed patents related specifically to solid-state battery technology will exceed 25,000 before the end of 2027.

The Race to Control the Next EV Generation

This immense patent volume is a key indicator of the high-stakes 'IP arms race' involving automakers (Toyota, BMW), battery manufacturers (Samsung SDI, CATL, LG Energy), and specialized startups (QuantumScape). Companies are filing patents aggressively to protect every aspect of the technology—from solid electrolyte composition and interface engineering to manufacturing techniques.

Reaching 25,000 patents by 2027 reflects the global nature of this competition and the high capital investment being poured into SSB research. The large patent volume suggests a complex licensing landscape is forming, which will ultimately determine the cost and accessibility of the next generation of energy storage.
