Zinergy

Founded in 2015 by researchers from the University of Cambridge, it designs its chemistry, synthesises materials and prints cells in volume on roll-to-roll lines. The batteries use a water-based electrolyte with no lithium or mercury and can be cut or punctured without catching fire. Standard products come in 1.5, 3.0, 4.5 and 6.0 V series, with the 6 V cells delivering peak pulses above 500 mA for NB-IoT and LTE-M. Zinergy has R&D in Europe and China and a 2,200 m2 production site in Shenzhen.

The 2025 Battery Report lists Zinergy among European zinc battery manufacturers.
