"large-scale... printed battery... organic energy storage with high power density, 5 kW/kg... voltage drop, which measures the self-discharge, is less than 0.5 V in 100 hours, which is a world record for energy storage with organic electrodes in water-based electrolytes... We must, however, increase the energy density... received the award for best Startup for Climate during the recent COP26 meeting... patented and is to be commercialised"
