The advantages of Ni-Fe batteries

With a century of retreat, NiFe batteries remain today the most mature and durable stationary storage system on the market.

The highest durability. A shelf life of several decades.
Very good resistance to limit conditions (overloads, deep discharges, short circuiting)
Contains no strategic metals (lithium) or heavy or toxic metals (lead, cadmium).
Alkaline electrolyte based on water and potash (KOH).
Thermal stability at 100%. No harmful gases emanate.
10000 cycles to 30% DoD.


To guide you step by step through the jungle energy storage systems and help you make the best technical and economical choice.
