What TeraWatt Technology does

TeraWatt Technology Inc. is a California-incorporated, privately-held battery developer and manufacturer founded in 2019, headquartered in San Francisco at 28 Geary St, Suite 650, with a wholly-owned Yokohama subsidiary for R&D and a mass production facility in Shizuoka, Japan that commenced initial operations in October 2024 and achieved ISO9001 certification in May 2025. The company designs and manufactures next-generation lithium-ion batteries focused on being lighter, smaller, more powerful, and safer than incumbents, targeting three primary use-case segments: electric mobility (EV batteries), grid-scale energy storage (with strategic partners JERA Co. and Kyuden International in the Japanese market), and industrial/infrastructure applications including port electrification and stationary storage.

The company's core technology platform pairs cell chemistry with "TeraSpace," an internal system that integrates AI and robot artisans into battery development and manufacturing, alongside a dedicated mass-production technology platform intended to bridge the gap between pilot and commercial-scale output. The company has filed no disclosed patents or trademarks, so its defensibility rests on manufacturing know-how, talent pedigree, and process IP. Operations follow a dual US-Japan model: US-side functions include headquarters, strategy, and international business development; Japan-side functions include R&D in Yokohama and manufacturing in Shizuoka, with a recently appointed Director of International Business Development targeting US, European, and broader Asian markets.

TeraWatt monetizes via direct B2B hardware sales — quote-based pricing on lithium-ion battery cells and packs sold to EV manufacturers, energy storage customers, and industrial buyers through enterprise offtake contracts. The go-to-market relies on enterprise field sales and strategic energy partnerships rather than channel intermediaries. The company has raised disclosed equity including a Series A (Khosla, Scrum), Series B led by Temasek (with Coral Capital, Daikin, JAFCO, Khosla, Scrum), a Pre-C round, a 500M yen (~US$3.35M) debt facility from SMBC, and a Series C that closed in April 2026 with ~US$10M from JERA Ventures plus Japan Green Investment, Kyuden International, and ITOCHU Technology Ventures. Strategic investors JERA and Kyuden are positioned to anchor commercial offtake into Japan's grid-scale storage market. Revenue is not publicly disclosed.

Scale indicators5 records

Recent moves8 records

Expansion highlights5 records

Broad incumbents

• Samsung SDI: Samsung SDI is a global Li-ion battery incumbent serving EVs, ESS, and electronics. It is a broad incumbent whose capabilities, scale, and pricing power set the competitive ceiling TeraWatt must beat; TeraWatt's Head of Product and Technology (Dr. Sunho Kang) is a former Samsung SDI executive.
• LG Energy Solution: LG Energy Solution is one of the world's largest Li-ion battery manufacturers with EV and ESS product lines. It is a key incumbent competitor in both target markets (EV OEMs and utility-scale storage).
• Panasonic Energy: Panasonic Energy is a major Li-ion battery manufacturer with deep Japanese OEM relationships (notably Tesla and Toyota). It is the dominant incumbent in TeraWatt's home Japanese market and a likely competitor for the same JERA and Kyuden storage contracts.
• CATL (Contemporary Amperex Technology): CATL is the world's largest battery manufacturer with dominant market share in EV and energy storage cells. It is the global benchmark for cost and scale and the primary long-term competitive threat to any new battery entrant.

Direct peers

• Enovix: Enovix develops next-generation lithium-ion batteries with a proprietary 3D cell architecture targeting consumer electronics and EVs. Similar to TeraWatt, it focuses on next-generation Li-ion performance improvements (energy density, safety) and is in early commercial scale-up.
• FREYR Battery: FREYR Battery was a next-generation lithium-ion battery cell manufacturer with a similar scale-up trajectory and talent base; it serves as the most directly comparable peer in stage, technology positioning, and the pilot-to-commercial transition that TeraWatt is now attempting. TeraWatt's VP of Strategy (Ryuta Kawaguchi) is a former FREYR CSO/CTO, underscoring the direct lineage.
• Microvast: Microvast is a commercial-stage lithium-ion battery manufacturer targeting commercial vehicles, industrial, and energy storage — directly overlapping TeraWatt's target segments (EV, industrial, stationary storage) with similar B2B enterprise sales motion and emphasis on safety/performance differentiation.

Emerging players

• Solid Power: Solid Power is a next-generation battery developer focused on sulfide-based solid-state technology with automotive OEM partnerships (BMW, Ford, SK On). It is an adjacent peer that competes for the same EV battery offtake contracts but with a differentiated solid-state chemistry.
• QuantumScape: QuantumScape develops solid-state lithium-metal batteries with Volkswagen as a key investor and customer. It targets the same premium EV battery segment that TeraWatt addresses with improved conventional Li-ion, making it an indirect competitive threat.
• Sila Nanotechnologies: Sila develops silicon-anode battery materials designed to drop into existing Li-ion manufacturing lines. It competes for the same next-generation battery narrative and OEM offtake pipeline, with Daimler as a key customer and investor.
