Factorial Energy’s solid-state batteries enabled a modified Mercedes EQS to travel over 745 miles without recharging.

The company collaborates with major automakers including Mercedes-Benz, Stellantis, and Hyundai to bring this technology to market.

A merger with Cartesian Growth Corporation III will provide $100 million in funding and a $1.1 billion valuation by mid-2026.

These batteries are expected to appear first in luxury and high-performance EVs, potentially boosting adoption in the US market by 2027.

The existing battery is not big enough and it’s not light enough, it’s not efficient enough.
— Dr. Siyu Huang, CEO of Factorial Energy, during an interview with The New York Times discussing the challenges of existing battery technologies.
