Extremely long life

  • Design lifetime is 40 years
  • Service life of 20 years with daily completely cycling for renewable integration
Safe icon

Inherently safe

  • Aqueous (water-based) electrolyte
  • Non-flammable and non-explosive
  • Electrodes do not contain toxic or rare metals, like lead (Pb), Cadmium (Cd), or Cobalt (Co)
  • The chemistry can handle continuous overcharging without experiencing thermal runaway
Hot and cold Icon with sun and snowflake

Robust operation

  • Operating temperature ranges from -40°C to +45°C
  • Able to withstand deep discharging and overcharging with no permanent damage to cell capacity
Leave icon

Environmentally friendly

  • Electrodes are composed of nickel (nickel oxide hydroxide) and magnetite (iron oxide), which are abundantly available in nature
  • 100% recycling metal compounds is possible due to the absence of alloy
