Innolith AG, a developer of rechargeable inorganic battery technology, announced it is developing a 1000 Wh/kg rechargeable battery. Under development in the company’s German laboratory, the new Innolith Energy Battery would be capable of powering an electric vehicle (EV) beyond 1000 km on a single charge, according to the company. The company also claims that the device would also radically reduce costs due to the avoidance of exotic and expensive materials combined with the very high energy density of the system.

Innolith adds that its battery would be the first non-flammable lithium-based battery for use in EVs. The battery uses a non-flammable inorganic electrolyte, unlike conventional EV batteries that use a flammable organic electrolyte.

“The EV revolution is currently stymied by the limitations of available batteries,” explained Sergey Buchin, CEO of Innolith AG. “Consumers want an adequate range on a single charge in an affordable EV, and confidence that it is not going to catch fire. The Innolith Energy Battery is the breakthrough technology that potentially can meet all these needs.”

Innolith will be bringing the Energy Battery to market via an initial pilot production in Germany, followed by licensing partnerships with major battery and automotive companies. Development and commercialization of the Energy Battery is anticipated to take between three and five years.

Innolith says it has used a conversional approach in the chemistry of its Energy Battery to generate the high energy density seen in each cell. Conversion reaction materials offer a route to high-energy-density battery cells as they overcome the poor performance of traditional intercalation-based materials. This new approach could enable batteries to reach cell-level energy content values that have never been possible before.

"This new breakthrough has been made possible by years of dedicated research into all aspects of inorganic electrolytes and their application to rechargeable batteries," commented Innolith Chairman, Alan Greenshields. "Simply put, the experience gained in how to build high-power batteries with exceptional robustness and cycle life has proved to be the right basis for building high-energy products too. The absence of organic materials, a key aspect of Innolith’s battery technology, removes the critical source of safety risk and chemical instability of high-energy batteries. It all fell into place in 2018 from an R&D perspective, with several extraordinary breakthroughs."
