XL Batteries' mission is to develop the largest batteries in the world. We will do it with chemistry built to be big.

​

The heart of our technology is novel chemistry for a 20+ year, non-flammable flow battery.

​

Our organic molecules for charge storage are stable in salt water and come from inexpensive, industrial feedstocks.

​

Pairing this novel, non-corrosive chemistry with the powerfully scalable architecture of flow batteries produces a system that is stable, safe, non-flammable, inexpensive in every component, and simple to scale.

​

Designed specifically for a flow battery architecture, our chemistry is built for the largest batteries in the world.
