Solid-State Battery Roadmap: Every Company and Timeline

Tracker for 20+ solid-state battery companies — chemistry, energy density, production timeline, and partnerships.

Key Highlights

  • 20+ solid-state companies tracked
  • Sulfide vs oxide vs polymer electrolytes
  • Energy density targets (400-500 Wh/kg)
  • Automotive OEM partnerships
  • Production timeline to 2030

Overview

A comprehensive roadmap tracking 20+ companies developing solid-state battery technology. Covers electrolyte chemistry, energy density targets, production timelines, and automotive partnerships.

What's Inside

Electrolyte Technologies

Sulfide electrolytes (Toyota, QuantumScape) offer high ionic conductivity but moisture sensitivity. Oxide electrolytes (Solid Power) are more stable but harder to manufacture. Polymer electrolytes (SES) are flexible but limited to lower temperatures.

Commercialization Timeline

Toyota targets 2027-2028 for solid-state EVs, Samsung SDI aims for 2027 pilot production, and QuantumScape targets 2025-2026 for initial automotive qualification.
