Ionblox
Ionblox is a Fremont, California battery company building high-energy, high-power lithium-ion cells around a proprietary pre-lithiated silicon (SiOx) anode. Spun out of the earlier Zenlabs Energy effort and rebranded in 2022, the company targets two demanding markets - electric vehicles and electric aviation (eVTOL) - with cells that it says exceed 330 Wh/kg and can charge to roughly 60% in five minutes while holding up past 1,000 cycles. Backed by eVTOL maker Lilium, Applied Ventures, Temasek and Catalus Capital, Ionblox has raised about $32M in Series B funding and holds more than 40 patents.
Jaunt Air Mobility
Jaunt Air Mobility is a Dallas-based aerospace company building the all-electric Journey eVTOL, an air taxi that takes off like a helicopter and cruises like an airplane using patented Slowed Rotor Compound (SRC) technology. Founded in 2019 on intellectual property acquired from Carter Aviation, Jaunt is pursuing a certification path as a rotorcraft and is now a brand within publicly traded AIRO Group Holdings. Its aircraft carries a pilot and four passengers roughly 80-120 miles at 175 mph with low noise and an autorotation safety fallback.
Pyka
Pyka builds large autonomous, all-electric aircraft for crop protection and cargo logistics. Headquartered in Alameda, California, the company designs its own airframes, batteries, flight computers, and autonomy stack, and flies them commercially across four continents for customers in agriculture, freight, and defense.
