EV Suppliers

Sion Power is a U.S. innovator in high-energy-density battery technology, focusing on lithium-metal and lithium-sulfur batteries. Founded in 1989, Sion Power’s Licerion technology combines lithium-metal anodes with advanced electrolytes to achieve energy densities up to 500 Wh/kg, targeting EV and aerospace applications. The company’s batteries promise longer range and lighter weight compared to traditional lithium-ion cells. Sion Power operates a pilot line in Tucson, Arizona, producing prototype cells for automotive and aviation testing. With partnerships like BASF and investments from Volkswagen, Sion Power is advancing toward commercial production. Its focus on safety and performance, including proprietary electrolyte formulations, positions it as a leader in next-generation battery solutions for electric mobility.

Factorial Energy is a U.S. developer of solid-state batteries for electric vehicles, focusing on high-energy-density and safe cells. Founded in 2019, Factorial’s FEST (Factorial Electrolyte System Technology) uses a proprietary solid electrolyte to enable lithium-metal anodes, achieving up to 450 Wh/kg energy density. The technology supports longer EV range, fast charging, and enhanced safety by eliminating flammable liquid electrolytes. Factorial has partnerships with Mercedes-Benz, Stellantis, and Hyundai for prototype testing and development. The company operates an R&D and pilot facility in Massachusetts, producing cells for automotive validation. Factorial’s scalable technology is designed for integration into existing manufacturing lines, accelerating commercialization. With significant funding and a focus on automotive-grade batteries, Factorial is positioned to lead the solid-state battery revolution for EVs.

QuantumScape is a Silicon Valley-based company pioneering solid-state battery technology for electric vehicles. Founded in 2010 and backed by Volkswagen, QuantumScape’s goal is to commercialize a lithium-metal solid-state battery that can deliver a step-change in energy density, charging speed, and safety. The company has developed a proprietary ceramic solid electrolyte separator that enables the use of a pure lithium metal anode, eliminating the graphite/silicon anode and thus significantly increasing energy per cell. In late 2020, QuantumScape publicly demonstrated single-layer cells with impressive performance, and has since been advancing to multi-layer cell prototypes. The technology promises up to 80% greater energy density than today’s Li-ion, and the ability to charge to 80% in 15 minutes, all while being safer (non-flammable) and with longer life. QuantumScape is in R&D phase with a pilot line (“QS-0”) in San Jose and plans for a larger pre-production line (“QS-1”) with VW in Germany. The company’s development timeline targets automotive sample deliveries in coming years and mass production mid-decade. As a high-profile startup with a successful public listing, QuantumScape has drawn attention for its potential to revolutionize EV batteries. While challenges remain in scaling and durability, QuantumScape’s solid-state cells represent one of the most promising pathways to dramatically improve EV range and convenience, and the company is intensely focused on turning that promise into commercial reality.

SES AI Corporation is a U.S.-based leader in lithium-metal battery technology for electric vehicles and urban air mobility. Founded in 2012 as a spin-out from MIT, SES develops hybrid lithium-metal cells with a proprietary high-energy electrolyte and AI-driven battery management software. Its batteries offer energy densities up to 400 Wh/kg, enabling longer EV range and lighter packs. SES operates pilot facilities in the U.S. and South Korea, producing prototype cells for partners like General Motors, Hyundai, and Honda. The company is building a gigafactory in Shanghai to scale production. SES’s AI platform optimizes battery performance and safety, addressing lithium-metal challenges like dendrite formation. As a publicly traded company, SES is poised to lead the transition to high-energy, fast-charging batteries for next-generation EVs.
