Why Is Everyone Trying to Build a Solid-State Battery?
Why Is Everyone Trying to Build a Solid-State Battery?Brian PotterJul 30, 2026ShareA battery technology that’s getting a lot of attention is solid-state batteries, lithium-ion batteries that replace the liquid electrolyte with a solid material. Chinese battery manufacturer CATL alone had more than 1,000 people devoted to solid-state battery research as of 2024, and battery manufacturers like BYD, LG, and Samsung are also working on the technology. US and European startups making solid-state batteries have collectively raised over $4 billion as of 2025.Solid-state batteries have several potential advantages over the lithium-ion batteries with liquid electrolyte we use now.
