GRST (Green, Renewable, Sustainable Technology) makes PFAS-free, water-recyclable, low CO2 lithium-ion battery binder which holds the active materials on the electrodes. GRST's binder is a simple drop-in to existing manufacturing processes and matches performance and cost of conventional binder. GRST has validated its technology at its 1 GWh scale cell factory and is scaling up by selling its materials to global battery manufacturers.

Notable Achievements

  • Raised over US$87 million
  • We have 1 GWh of binder production and cell/electrode production in China
  • Won the Earthshot Prize in 2023 Clean Our Air; finalists for 2026 Zayed Sustainability Prize
