Silicon Valley startup TeraWatt Technology has announced that its prototype 4.5 Ah solid-state battery design achieved a record-breaking energy density of 1,122 Wh/L (432 Wh/kg) in validation tests conducted by third parties, including the Japanese testing service TOYO System.
TeraWatt says this 4.5 Ah design, which is branded as TERA3.0, will be available for select early adopters in 2021 and for full release in 2022. The company continues to further iterate the TERA3.0, and is developing additional designs, including different cell formats, sizes and energy capacities.
TeraWatt Technology was established in 2017 as a division of SF Motors (dba SERES), a transportation tech company with headquarters in Santa Clara, California. The team has opened itself to strategic partnerships and external investment.
SERES Senior Manager Ken Ogata said, “TERA3.0 is a significant step beyond the traditional lithium-ion solutions that have dominated for the past 30 years. Through our solid-state technologies, consumers will be enjoying longer-lasting, safer and more reliable devices sooner. Since TERA3.0 is designed for mass production using current lithium-ion production equipment, we can accelerate mass adoption without imposing a massive financial burden to manufacturers and consumers.”
