Factorial Energy, a company at the forefront of solid-state battery technology, has announced its decision to go public through a merger with a Special Purpose Acquisition Company (SPAC). The move is aimed at accelerating the development and commercialization of its next-generation battery cells, an area in which the company has been investing for several years while building strong partnerships with major automotive manufacturers.
The chosen partner for the transaction is Cartesian Growth Corporation III, a SPAC already listed on the stock market and created specifically to acquire and merge with an operating company. This route to public markets has become increasingly common in the advanced battery sector, with other players such as StoreDot – one of Factorial’s main competitors – having followed a similar path in the past.
Through the merger with Cartesian Growth Corporation III, Factorial expects to significantly strengthen its capital base. The transaction is set to bring in a total of 376 million dollars in new funding. Around 100 million dollars will come from fresh capital committed by institutional investors via a private investment in public equity (PIPE). The remaining 276 million dollars are held in a trust fund by the SPAC itself. However, this portion of the capital could be partially returned over time to investors who decide not to approve the merger or choose to redeem their shares. Factorial is currently valued at approximately 1.1 billion dollars. Following the completion of the merger, the valuation of the combined public company is expected to rise to around 1.5 billion dollars, reflecting both the new capital injection and market expectations surrounding solid-state battery technology.
The company’s appeal is closely tied to its strategic collaborations with some of the world’s leading automotive groups. Factorial already counts Mercedes-Benz, Stellantis, and Hyundai-Kia among its partners and investors. These manufacturers have backed the company not only financially but also from an industrial standpoint, with the intention of integrating Factorial’s solid-state batteries into future electric vehicle platforms once mass production becomes viable.
Solid-state batteries are widely seen as a key breakthrough for the electric mobility sector, promising higher energy density, improved safety, and faster charging compared to conventional lithium-ion batteries. By becoming a publicly traded company, Factorial aims to secure the financial resources needed to scale up research, pilot production, and eventually large-scale manufacturing.
With strong industrial partners, a growing capital base, and increasing interest from the market, Factorial Energy’s SPAC merger marks an important step in its ambition to play a leading role in the next generation of energy storage technologies.
