INNOLITH introduces I-STATE Power Cell for high performance e-mobility

Innolith, a European developer of Li-ion battery cell technologies, introduced the I-State Power Cell, a battery cell specifically designed for the most demanding e-mobility applications. The new cell will be used to drive sports and luxury battery electric vehicles (BEV), industrial vehicles and electric aviation.

In an official partnership for the new cell, Innolith will be supplying the new I-State Power Cell to electric aviation company Væridion to power electric Conventional Take-Off and Landing (eCTOL).

The I-State Power Cell is based on NMC/graphite electrode technology in a full 21700 cell format, but using Innolith’s proprietary non-flammable liquid electrolyte that extends voltage cut-off to 4.6V with NMC and 5.0V with other cathode materials.

This enables the cell to deliver top end energy density of 280 Wh/kg, with rapid 3C discharge rates for constant current and long cycle life of more than 800 cycles at 1C. To power performance applications such as sports cars and e-aviation, the cell can also deliver pulse currents of 5C for 60 seconds, 8C for 30 seconds and up to 15C for 10 seconds.  The cell also supports fast charging from 10% to 80% SoC in 12 mins while demonstrating some of the lowest internal resistance numbers amongst 21700 cells in the market.

The I-State Power Cell will be used for e-mobility applications that require high-energy density battery capable of delivering high power. The cells are planned to be manufactured through licensing agreements with battery manufacturers, with the advantage that the cells can be produced using existing Li-ion production lines and raw materials.

The Power Cell costs per kWh are expected to be even lower than conventional Li-ion batteries as the higher voltage enabled by the liquid inorganic electrolyte enables higher utilization of cathode capacity and lower the amount of expensive active materials that are required in a cell.  The Power Cell also has significant environmental advantages with near complete recyclability of the electrolyte salt and solvent.

Innolith announced in June 2023 the commercialization of its new battery technology, I-State Energy Cell, which uses a non-flammable, liquid inorganic electrolyte with properties that are optimal for mass and specialized e-mobility applications. (Earlier post.) The I-State’s electrolyte qualities allow it to operate at higher voltages than traditional Li-Ion batteries, whilst improving safety and remain operational between a temperature range of -40- +60.

Innolith has completed testing of the Power Cell in full 21700 format in partnership with independent third-party testing organisations and industry partners. Innolith says that it is currently at the final stages of negotiations with auto and battery OEMs in Europe, Asia and USA for joint cell development and further commercialization of its I-State technology.
