HPB reaches milestone in all-solid-state battery development

As a successor to lithium-ion batteries, this technology gracefully solves the major hurdles of continuous production of all-solid-state batteries.

The company High Performance Battery (HPB) has developed the world's first solid-state battery whose core – unlike all other solid-state battery projects – is the result of a chemical reaction within the battery. Whereas solid ion conductors are usually inserted into the battery as prefabricated parts, the HPB solid ion conductor is first created in the battery cell, similar to a "two-component glue". As a result, this technology elegantly solves significant hurdles for the series production of solid-state batteries as a possible successor technology to lithium-ion batteries.

"The development of the solid-state battery is a great success for green energy and eMobility. The establishment of the first production offers the opportunity to position ourselves as a technology leader on the global market. In addition to selling the licences and preparing for the start of production, we are continuing to optimise the battery cell in terms of size and capacity," says Dr Thomas Lützenrath, COO of High Performance Battery.

The innovative battery technology of the High Performance Battery, as per the company, has an extremely long service life without loss of performance at almost constant capacity. Furthermore, the solid state battery is resistant to deep discharge and fast charging, the solid ion conductor is non-flammable and, thus, safe to use. In addition, the new technology has a 50 per cent improved environmental balance compared to conventional lithium-ion batteries and does not require the controversial raw material cobalt. The innovative battery cell has already proven its basic functionality in initial tests.

The new battery technology from High Performance Battery serves a broad field of applications: it has a high potential to be used in e-mobility – on land, on water and in the air – in the future. In particular, it is suitable for domestic energy supply and the intermediate storage of volatile electricity.

Market development is also unconventional: HBP grants licences to producers and users for attractive market segments. The production start of the first production line of 200 megawatt hours is planned for 2023. The modular structure of the production is intended to enable short-term entry and easy scaling to the gigafactory level.
