The Power of Stacking

Unparalleled Safety

Don’t get burned by your battery choice. Choose safety and performance with our vanadium flow batteries. Unlike lithium-ion options prone to thermal runaway, our non-flammable, non-explosive technology guarantees safety to people and property. Engineered to the highest standards, it’s a choice your insurance company will appreciate.

Superior Economics

At four (4) hours or more of discharge, CellCube’s vanadium flow battery is economically superior to other solutions. Add to that the many cost-saving benefits – near-zero degradation, a cycle life of more than 20,000 cycles, no need to repower, minimal operating maintenance, and full re-usability of the vanadium electrolyte at end of life – and you achieve vastly superior economic results. Top it all off with the peace of mind that comes with no fire hazard risks and lower insurance premiums, and CellCube is clearly the superior solution for your large-scale utility and critical-infrastructure C&I applications.   

Superior Economics

Powerful Chemistry

Vanadium is abundant and increasingly sourced from secondary sources like spent catalyst and waste streams from the steel industry.  It is non-degrading and preserves value indefinitely. When its unique properties are applied in vanadium flow batteries, it offers superior durability, reliability, and virtually infinite reusability.

CellCube long-duration batteries combine reversible single element electrochemical reactions with simple rebalancing to ensure near-zero degradation and 100% throughput over more than 20,000 charging and discharging cycles – regardless of frequency, depth of discharge or ambient temperature.

True Sustainability:

CellCube systems embody sustainability, boasting a lifespan that exceeds lithium-ion by 2X+ and aligns with circular economy principles. Our vanadium electrolyte, sourced from U.S. steel-making waste streams, is nearly 100% reusable, and most remaining system components are recyclable, supporting a zero-waste model. With 78% lower CO2 emissions than lithium-ion, we help you achieve more of your environmental goals.
