years of
basic research

Since the beginning of his scientific career, Günther Hambitzer has pursued his vision of solving battery ageing at its chemical root causes. The foundation was already laid in his 1989 dissertation, in which he was able to trace battery ageing in organic systems back to side reactions. With his habilitation in 1995, he formulated the foundations for a novel high-energy battery system. Since then, he has been pushing its further development to market maturity, both on a scientific and entrepreneurial level.


environmental balance

No critical raw materials are needed for the production. This also contributes to the overall improvement of the environmental balance by more than half compared to conventional lithium-ion batteries.

(These values were calculated by independent experts.)



A precursor technology (still liquid-based) has already successfully completed more than 50,000 charging cycles and has been in use for grid stabilisation in the USA since 2017. The HPB solid-state batteries have been running for more than 12,500 cycles compared to conventional lithium-ion batteries with 1,250 cycles (1C/1C at 0-100% state of charge).
