30

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.

50%

better
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.)

>10.000

charging
cycles

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).

Press release HPB

HPB takes part in the Bobsleigh World Championships in Winterberg.

The sport of bobsleigh shows more than almost any other sport that high performance and low temperatures go together wonderfully. This is why HPB Holding AG has decided to tap into a field of sponsorship that is unusual for battery companies: Winter sports.

StartUp aus Bonn: Elektro-Batterie der Zukunft

[WDR5 – Linda Staude]

Heute mit Linda Staude. Hallo und herzlich willkommen.
Große Entdeckungen sind manchmal das Produkt eines glücklichen Zufalls. Eine der bekanntesten ist ein unerwünschter Schimmelpilz auf einem vergessenen Laborexperiment, der dann plötzlich alle möglichen Bakterien tötet. Besser bekannt ist er als Penicillin. Solche Zufälle gibt es offenbar immer noch:

[Sebastian Heinz]

Das war das Forschungsziel, die Batteriealterung aufzulösen und mit der Lösung sind wir über den Feststoffakku gestolpert. Also, die Entdeckung des Feststoffakkus war im Grunde genommen unser Penicillin-Moment.

[WDR5 – Linda Staude]

Was hinter den Penicillin Moment des Bonner Unternehmers Sebastian Heinz steckt, das verraten wir Ihnen später in dieser halben Stunde.

Ewiger Akku? Das große Versprechen der neuen deutschen Wunderbatterie

Bislang hemmt vor allem die kurze Lebensdauer von Stromspeichern die Verkehrs- und Energiewende. Doch nun will ein Bonner Unternehmen mit einer neuen Batterie genau dieses Problem gelöst haben. Die Autoindustrie hat bereits Interesse angemeldet.
