A group of scientists from the Bonn-based company High Performance Battery (HPB), led by Prof. Dr. Günther Hambitzer, has made a major breakthrough in battery and storage technology. They have developed the world's first solid-state battery with remarkable properties, ready for production.
The applications span from stationary storage for residential and industrial purposes to charging infrastructures and the mobility sector, specifically the automotive industry. The data and properties measured thus far exhibit markedly superior values and characteristics when compared to the presently prevalent lithium-ion batteries.
- Longevity
Conventional lithium-ion batteries typically require replacement after approximately 1,250 charging cycles, based on hourly charging and discharging. In contrast, the HPB solid-state battery boasts a minimum of 12,500 charging cycles under comparable load conditions. It is important to note that these cells have not yet reached their end of life, and this number is expected to steadily increase over time.
- Safety
The new HPB solid-state electrolyte is non-flammable and thus considerably safer than the flammable liquid electrolytes of conventional lithium-ion batteries.
- Sustainability
The HPB solid-state battery shows a 50 percent better environmental balance compared to current lithium-ion technology. This makes it the “green key to the energy and mobility revolution”.
- Conductivity
Compared to the liquid electrolytes commonly used today, the HPB solid-state electrolyte has an enormously improved conductivity. This is decisive for the available power from the battery cell. The HPB solid-state electrolyte shows an absolutely higher conductivity at minus 40 °C than conventional liquid electrolytes at their optimum at plus 60 °C. These properties have been confirmed by independent partners and research institutes in the temperature range from minus 40 °C to plus 60 °C.
In conclusion, the groundbreaking development of the HPB solid-state battery signifies a monumental leap forward in energy storage technology. With its exceptional longevity, enhanced safety, superior sustainability, and higher conductivity, it not only surpasses conventional lithium-ion batteries in all aspects but is poised to be a game-changer in the energy and mobility sectors. This innovative solution, backed by rigorous scientific research, holds the promise to spearhead the next generation of energy storage and power supply. It indeed embodies the potential to be the 'green key' to a sustainable future.
