THE LITHIUM PARADOX

Lithium Ion batteries cannot meet all market needs.

The market for energy storage technologies is polarizing as there is no “One size fits all” solution.

DOWNSIDE TO LITHIUM BATTERIES

Lithium batteries are ideal for short duration power-intensive applications in mobility, such as mobile devices and electric vehicles;
Lithium-based batteries have inherently shorter lifetimes;
Lithium-based batteries lose capacity rapidly over time;
They are not economically-efficient enough for the larger grid scale installations with longer duration storage (4+ hours). Thus they cannot support the foreseeable amount of renewable energy expected to be installed;
They have a high cost of end-of-life processing.

BENEFITS OF VANADIUM FLOW BATTERIES

Vanadium flow batteries outperform lithium for grid scale installations.
Their cost decreases for longer durations (economies of scale).
They deliver 100% Depth-of-Discharge (DoD) without loss of capacity for the whole 25-year lifetime or 15,000 cycles.
Vanadium presents better safety characteristics being non-flammable and non-explosive, and they carry an end of life value.

Lithium batteries have been deployed for residential storage and grid-scale projects despite not being the ideal technology for long duration stationary application.

Thanks to the vanadium technology, we now have a better alternative!

RESIDENTIAL AND POWER BACK-UP

Our Technical Team in Fuel Cells, Vanadium Flow Batteries and cogeneration have spent years conceptualizing StorEn’s residential batteries.

Our batteries deliver 100% of their initial capacity throughout their 25-year lifetime (or 15,000 cycles). The vanadium electrolyte is not subject to chemical degradation over use, unlike lithium batteries, and can be reused indefinitely.

Our patented Multigrids™ stack design delivers the leading power density in the world, while reducing by over 50% the cost of the power side of the battery.

The standard 20-year duration typical of vanadium flow batteries can be exceeded thanks to our patented Equilevels™ and Resafe™ that extend the duration of StorEn batteries to over 15,000 cycles, eliminating service inspections and reducing maintenance costs.

Our batteries use a proprietary water-based electrolyte chemistry that is non-flammable and non-explosive. StorEn’s electrolyte increases the energy density of the battery by about +25%, and this translates into a much smaller battery at energy parity.

The result of StorEn R&D activities are modules with the highest power density and the smallest size, a modular architecture to satisfy the widest array of customers’ homes and installation requirements, and the lowest cost/cycle possible today, below the one of lithium batteries.

StorEn is a member and supports the mission of advancing zero-energy green buildings and LEED.
