About Factorial Energy
FEST uses a lithium-metal anode and proprietary electrolyte to increase energy density while retaining compatibility with much of the equipment used for conventional lithium-ion cell production. Factorial says approximately 80% of the manufacturing process can use existing production infrastructure, supporting a more practical transition into higher-energy cells.
Solstice moves further toward an all-solid-state architecture using a dry cathode process developed with Mercedes-Benz. Factorial is adapting the technology into aerospace and robotic battery packs as well as automotive cells, with UAV testing demonstrating how higher specific energy can translate directly into additional flight range.

Timeline
Events
- 2026-07-24 - Commercial Order - Factorial secures its first commercial drone-battery order
Factorial describes the order as its first commercial aerospace order. The milestone moves its drone-battery work from testing and integration into commercial supply.
Source - 2026-07-13 - Partnership - Factorial Energy and Tulip Tech advance UAV batteries after 30% range gain
The companies are moving from customer flight validation into joint customer engagement and a roadmap toward volume production. Tulip Tech is integrating Factorial cells into custom high-density battery packs for commercial, industrial and defence UAVs. The test result was achieved before engineering optimisation, giving the partners a measured baseline for the commercial programme.

The completed pack was the first North American automotive integration of Factorial solid-state cells. A patented mechanical architecture adapted the STLA Large battery pack and control systems to FEST cells. Road testing began to validate charging, driving performance, reliability and vehicle safety.

The combined public company retained the Factorial Energy name and listed its common stock and warrants as FAC and FACWW. The transaction implied an equity value of approximately $1.3 billion. Factorial said the closing provided more than $100 million in gross proceeds for battery commercialisation.

The test vehicle covered 1,205 km through Germany and Denmark to Sweden on public roads. It arrived without a charging stop and retained 132 km of indicated range. The completed run extended Mercedes and Factorial real-world validation across varied climates and routes.
Source - 2025-02-24 - Demonstration - Factorial and Mercedes put lithium-metal solid-state EQS on the road
The prototype battery was integrated into a lightly modified EQS after bench testing. The pack targeted up to 25% more range at comparable weight and size with passive cooling. Mercedes-AMG High Performance Powertrains and Factorial engineers supported the real-world validation programme.
