  • Battery energy storage is essential for renewable energy and transportation
  • The mostly used Li-ion battery has problems of flaming concern and long charging time
  • Application of battery swapping is limited by the battery pack models and the high cost of battery packs
  • The battery energy storage market will draw $620 billion investment by 2040, forecasted by Bloomberg

  • Inherently safe: ZIBB uses water-based electrolyte, which is inherently non-flammable.
  • Fast refuelling: On EV application, ZIBB can be refuelled simply by swapping liquid chemical in tanks, without limitation on battery models. The swapped electrolytes can be regenerated by off-site charging
  • High energy density: ZIBB holds the world record of energy density (101Wh L-1) in aqueous flow batteries
  • Scalability: The flow battery design can be readily scaled-up for automobile and large-scale grid energy storage application

  • Electric vehicles
  • Automobile and grid-level energy storage system
