Solid-State Battery Electrolyte Materials: Startups and Suppliers Landscape
This analysis examines the solid-state battery electrolyte materials landscape as of late 2025. Seventeen US and European startups have raised over $4.2 billion combined, with Factorial Energy, QuantumScape ($1.5B total funding), Solid Power ($437M), SES AI ($600M), Lyten ($367M+), and Adden Energy ($20M) among the leaders. Toyota dominates the patent landscape with 8,200+ granted solid-state battery patents from 2020-2023, followed by LG, Samsung, Murata, and Panasonic. Key material suppliers include Ampcera (scaling to 1,000 tons by 2027), NEI Corporation (multiple electrolyte compositions), Solid Ionics (1,200-ton capacity planned for Ulsan by 2027), MSE Supplies, Lorad Chemical, and Niterra (LLZO specialist). The Toyota-Idemitsu Kosan partnership represents a $142M investment in lithium sulfide production for 2027-2028 commercial launch. Commercial deployment is projected for 2027-2030 in premium EVs, with semi-solid batteries reaching market earlier than fully solid alternatives. Enterprise R&D intelligence platforms like Cypris enable continuous monitoring of this rapidly evolving landscape across patents, startups, suppliers, and partnerships.
