April 18, 2019: Innolith, the German start-up that rose from the ashes of Alevo, reported on April 4 that it has developed the world’s first 1,000 Wh/kg rechargeable lithium battery — giving an electric vehicle the potential of reaching 1,000km per charge.
Under development in the company’s German laboratory, the Innolith battery uses a non-flammable inorganic electrolyte and conversion reaction materials — although the company would not say what those materials are at this stage.
A company spokesman told ESJ the results had been achieved in the firm’s R&D laboratories in Bruchsal and that commercial production was around three to five years away.
To put this in context, Panasonic’s 2170 cells used in Tesla’s Model 3 are around 250Wh/kg. UK firm Oxis Energy has achieved 425Wh/kg to date, and hopes to reach 500Wh/kg later this year with its lithium sulfur technology, although its cells are not commercially available.
Sergey Buchin, CEO of Innolith, said: “The EV revolution is stymied by the limitations of available batteries. Consumers want an adequate range on a single charge in an affordable EV, and confidence that it is not going to catch fire.”
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.
Innolith has patents pending for the key inventions of the Energy Battery and is also maintaining commercial confidentiality on the cell chemistry mechanism.
Innolith’s non-flammable, inorganic rechargeable batteries are being used in its technology on the US PJM grid to provide fast frequency regulation services. The battery has operated for more than 55,000 full depth of discharge cycles.
