Since the beginning of his scientific career, our company founder Prof. Dr. Günther Hambitzer has been pursuing his vision of solving the problem of battery ageing at its chemical root. The cornerstone was laid as early as 1989 with his doctoral thesis, in which he was able to trace battery ageing in organic systems back to side reactions. With his habilitation in 1995, he formulated the basics for a new high-energy system. The discovery of the HPB Solid-State Electrolyte was his penicillin moment.

Longer lasting.

10x longer cycle life 

Greener.

Up to 50 % better­ environmental balance 

One technology – many options

 The HPB Solid-State Battery allows manufacturers to scale efficiently, businesses to build safer and more reliable solutions, and consumers to trust in power that lasts. Thanks to the modular design, it can serve various stationary fields of application from small (e.g. home storage) to large (e.g. industrial buffers).

Press release HPB

Independently verified: HPB Solid-State Battery passes PV8450 abuse tests without fire

→ External testing by ZSW in Ulm: seven abuse tests according to test specification PV8450-2021

→ No rupture, no fire, no explosion – in none of the test scenarios carried out

→ Even under nail penetration, internal short circuit and thermal load, the cells stay below the critical hazard levels

→ HPB CEO Dr. Sebastian Heinz: “With our technology, safety is not a protection system bolted on afterwards. It is a property of the cell chemistry itself.”



The HPB Solid-State Battery has passed a comprehensive series of safety and abuse tests according to test specification PV8450-2021. The tests were carried out externally and independently by the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Ulm, one of Europe’s leading test centres for battery safety. In none of the seven test scenarios did rupture, fire or explosion occur. An independent testing institution has thus confirmed that the solid electrolyte concept developed by HPB remains controllable even under extreme mechanical, thermal and electrical load.
