Technology

XL Batteries has created a breakthrough organic flow battery using proprietary, organic, low-cost electrolytes instead of scarce, corrosive vanadium. XL’s organic flow battery is made from abundant commodity chemicals and commercially available pumps, tubes and tanks – eliminating the need for specialized infrastructure or supply chains. By leveraging proven flow battery architecture with proprietary chemistry, XL Batteries enables mass deployment to support industrial users – such as data centers and manufacturing – as well as utilities and independent power producers.

Deployed broadly, XL’s organic flow batteries will –

  • Support the grid as it faces exploding energy demand from data centers and mass electrification
  • Offer a low-cost, non-flammable and long duration alternative to lithium-ion batteries
  • Enable the expansion of renewable power generation
  • Reduce dependence on coal, oil and supply-chain-constrained lithium
  • Mitigate the effects of burning fossil fuels for energy generation

Key Benefits

Minimal Technology Risk
XL Batteries builds on proven, scalable and reliable flow battery architecture eliminating unnecessary costs and risks.

Superior Battery Economics
XL Batteries uses inexpensive, widely available chemical feedstocks and materials, creating a lower CAPEX and lifetime cost of energy storage.

High Round-Trip Efficiency
With 70%+ round-trip efficiency, XL Batteries’ technology significantly outperforms most energy storage solutions. This is critical for utility-scale applications where low efficiency can drive up costs and force overbuilding of energy generation capacity.

Customizable & Flexible Storage Solutions
XL Batteries’ organic flow battery allows energy output and storage size to be scaled independently, meeting virtually any power need.

Use of Globally Ubiquitous Materials
Organic flow batteries can be produced domestically around the world. By relying on globally ubiquitous organic molecules and materials, XL Batteries’ organic flow batteries can boost global energy security and grid resilience.

Safety
Safety is non-negotiable. XL Batteries’ organic flow battery is safe, non-toxic, non-flammable and non-corrosive, providing an ideal alternative to lithium-ion batteries without the fire risks.

Durability
We expect XL organic flow batteries to last much longer than the 20-year industry standard.
