Market segment:


The need

Low-cost scalable recyclable batteries based on NiCd and NiMH chemistry use expensive materials, most specifically cadmium, which is toxic and prohibited for use in certain applications and areas.

The solution

Innovative fast-charging, nickel-iron batteries.

In using an iron-based anode material, customers have the potential to develop fast-charging nickel-iron batteries at a material low cost, using non-toxic anode materials.

The value proposition

Low-cost, non-toxic anode materials and designed for cell or battery manufacturers, a simple replace system enables easy servicing and extends the lifetime of the recyclable products at a significantly low cost.
