TeraWatt Technology

TeraWatt Technology Inc. is a specialized manufacturer of next-generation lithium-ion batteries, focusing on designs with high energy density, significant power, and enhanced safety features. The company was established in December 2019 and officially founded in January 2020 by Co-founder and CEO Ken Ogata, Ph.D. Initially a division of SF Motors (d.b.a. SERES), TeraWatt Technology became an independent company in January 2020, operating with R&D centers in Santa Clara, California, and Tokyo, Japan.

The company's primary business involves the design, development, and production of proprietary lithium-ion batteries engineered to offer superior energy and power density. This positions the firm to serve clients in demanding sectors such as automotive, consumer electronics, drones, and renewable energy storage. Its business model is centered on manufacturing and selling these advanced battery cells, targeting industrial clients who require long-lasting and reliable power alternatives. A key aspect of its strategy is designing products for mass production using existing lithium-ion manufacturing infrastructure, which helps accelerate market adoption by reducing the financial burden on manufacturers.

TeraWatt Technology has made significant technical strides, with its TERA3.0 prototype, a 4.5Ah solid-state battery, achieving a record-breaking energy density of 432Wh/kg (1122Wh/L) in third-party validation tests. The company is also developing its TERA4.0 line, aimed at electric vehicle applications with a target energy density of over 500Wh/kg. To scale its operations, the company completed its first mass production facility in Shizuoka, Japan, which began preliminary operations in September 2024 and received ISO9001:2015 certification in April 2025. This facility enables a seamless transition from R&D to mass production, with commercial sales expected to begin in 2026. The company has successfully raised significant capital through multiple funding rounds, including a Series C in July 2025, to finance the expansion of its production capacity. Investors include Khosla Ventures, Temasek, Development Bank of Japan, and Japan Bank for International Cooperation.
