# Solid-State Batteries in 2026: What's Actually in Production vs What's Still a Lab Demo Solid-state batteries have been "2 years away" for a decade. In 2026, the picture is more nuanced — some things are genuinely happening, others remain distant. **What's actually shipping:** - Toyota has delivered first solid-state cells to select EV platform testing (not consumer vehicles) - Samsung SDI's semi-solid electrolyte cells (hybrid approach) are in limited automotive supply - Solid Power (BMW/Ford partnership) has delivered engineering samples **What's still a lab demo:** - True all-solid cells with 500+ charge cycle stability at commercial cost - Dendrite suppression at high charge rates without performance degradation **The manufacturing gap**: The problem is not chemistry — it's manufacturing. Depositing solid electrolyte at micron-level consistency, at scale, at cost, remains unsolved. → [Full solid-state battery reality check →](/node/1410)
