Blue Current, Inc.
Blue Current is a Hayward, California solid-state battery developer building what it calls a 'silicon-first,' fully dry battery platform. Its Silicon Elastic Composite chemistry ties glass-ceramic electrolyte particles to silicon anode particles with compliant polymers, constraining silicon swelling so high-silicon cells can cycle stably at low pressure without flammable liquids or PFAS. Positioned as a safety-focused, B2B licensing and pilot-manufacturing company, Blue Current targets electric mobility, grid-scale storage, and consumer devices, and closed an $80M+ Series D extension led by Amazon in December 2025.
Qnovo
Qnovo is a Milpitas, California software company that makes lithium-ion batteries smarter. Its intelligent battery management platform - powering SpectralX adaptive fast charging and SentinelX safety diagnostics - is embedded in more than 150 million smartphones and increasingly in EVs from the world's top automakers, helping prevent fires, extend range, and stretch battery life.
Voltaiq
Voltaiq is a Berkeley-based enterprise software company that pioneered the category of 'battery intelligence.' Its Enterprise Battery Intelligence (EBI) platform automatically collects, cleans, and harmonizes data from battery test and production equipment, then surfaces the performance, quality, health, and safety insights engineers need to build better batteries faster. Founded in 2012 by UC Berkeley PhDs Tal Sholklapper and Eli Leland, Voltaiq is used by automakers, consumer-electronics giants, and energy-storage companies including Mercedes-Benz, Toyota, Amazon, Meta, and Sila to accelerate product development and catch defects weeks earlier than traditional QC.
Titan Advanced Energy Solutions
Titan Advanced Energy Solutions is a Salem, Massachusetts battery-tech company that uses non-destructive ultrasound and industrial AI to inspect lithium-ion cells at production speed. Its IonSight Digital Teardown platform images the inside of every cell on a manufacturing line - catching layer misalignment, contamination, dry zones, and other hidden defects that CT sampling and electrical tests miss - to improve battery quality, safety, and yield for EVs, grid storage, and consumer electronics.
Element Energy
Element Energy is a Menlo Park battery management company that uses semiconductor-grade hardware, software, and cell-level controls to extend battery life, prevent fires, and give retired EV batteries a second career on the grid.
