Innolith begins commercializing I-State battery technology; liquid inorganic electrolyte

Innolith, a European developer of Li-ion battery cell technologies, has begun the commercialization of its I-State battery technology platform for use in electric vehicles (EVs) and e-mobility applications. The company says that I-State will cut EV costs and increase vehicle range through a high energy density of 300 Wh/kg (NMC811/Graphite) while improving both safety and performance. This is made possible through its high voltage, high conductivity, non-flammable electrolyte that also enables an improved temperature range of -40 ˚C to +60 ˚C.

The Innolith proprietary liquid inorganic electrolyte can operate at up to 5 volts without degradation, unlike the Li-ion batteries in use today that are limited to 4.2 volts. This gives the batteries higher gravimetric energy density of 300 Wh/kg and volumetric energy density of 825 Wh/L.

The higher voltage of the cells enables higher utilization of cathode capacity through usage of nearly 100% of available Lithium vs 80% for Li-ion, over many stable cycles, and at high charge and discharge rates, the company says.

The I-State higher voltage enables a significant reduction of cathode metals used in the cell, helping EV manufacturers to cut costs and produce vehicles that are closer to the cost of Internal Combustion Engine (ICE) vehicles. The 20% reduction of lithium, cobalt and nickel will help alleviate environmental and sourcing concerns, while typically reducing the weight of an EV battery pack by 7% to 8%.

Innolith further said that I-State enables stable cycling of manganese containing cathodes with reduced content of nickel. The company is developing LMR (Mn-rich NMC) and LNMO chemistries jointly with several large and well-known partners in the market.

Additionally, Innolith further announces that new technologies based on the I-State platform are in development to provide for both increased EV range with 350-400 Wh/kg energy densities, and for lower-cost EVs with lower CO2 footprint due to reduced use of expensive green metals versus existing commercial cells in the market.

To complete a full range of technology development options, I-State is proven as a platform for development of LFMP and Na-based cells, where the first patent applications have been made by Innolith already in 2020-2022.

In addition to a high energy cell, Innolith has recently developed a high power cell on the same I-State platform. Development of the high-power cell that still retains exceptional energy density was possible due to the high conductivity of the I-State electrolyte (up to four times that of conventional Li-ion electrolyte).

To support its ongoing licensing negotiations, the company has signed Memoranda of Understanding (MoU) with five customers for a production requirement of 100 MWh per year. The MOUs are for applications across the off-road, aviation and mining sectors, and include an agreement with Xerotech, a leader in battery pack technology for heavy-duty non-road mobile machinery, to develop battery packs for the electrification of a wide range of applications.

In the automotive sector, Innolith is working closely with three of the 10 largest car companies and has recently signed an MOU with one of the leading EV manufacturers.

The Innolith I-State technology meets the charge, discharge and cycle life requirements of the major EV manufacturers and has been evaluated by leading testing and validation organisations as well as multiple automotive and battery OEMs and end-user companies across a number of industries. In addition to its use for EVs, Innolith will be marketing its I-State technology for applications in aviation, construction, mining, marine, rail and industrial sectors.

The I-State platform will be manufactured through licensing partnerships with automotive, industrial and battery companies with further details to be announced.



Oh boy it is the new story from Alevo bankruptcy, Alevo originated from Fortum failure ...

A 30 years soap with SO2 based electrolyte begin as a German project in the 80's.

Eikeland face a +$200M lawsuit from Dmitri Rybolovlev in Alevo.


Editor’s note:

Questions about a possible relationship between Alevo and Innolith have been raised before -- so much so that Innolith has a detailed FAQ entry ( addressing the issue.

Excerpts from the FAQ:

Our technology inventors – Dr. Laurent Zinck and Markus Borck – worked over 18 years, starting in 2000, in research and development of inorganic liquid electrolyte technologies. During those years they had worked in the multiple battery start-ups until five years ago they decided to set up their own – and Innolith was born. …

Laurent and Markus worked in ALEVO from the start and until the company filed for bankruptcy in 2017. They were employed to run the R&D team in Germany, reporting to the CTO of ALEVO. Both had never been members of the management team of ALEVO, not to mention that there was no investment or other form of entrepreneurial engagement with the team of businessmen who founded and ran ALEVO. …

After Innolith was established and funded by new investors in 2018, Laurent and Markus received financial means to bid amongst other contenders for the assets of failed ALEVO. Innolith made a successful bid for purchase of the IP sold by the bankruptcy administration of ALEVO. As a poison pill with the IP, ALEVO sold to Innolith some old projects in the US and the production site in Switzerland. All of those projects have been closed step by step during 2019-2020. IP portfolio of ALEVO still belongs to Innolith as it consists of the basic background patents of the inorganic liquid electrolyte (future I-State technology developed on its own by Innolith). …

ALEVO used to develop a power cell technology suitable mainly for grid frequency regulation. [Ed: GridBank] Innolith validated this technology in 2019 after purchasing of the IP and old projects of ALEVO, and arrived to the conclusion that a new invention of Innolith team made on its own in 2018-2019 of electrolyte suitable for energy cell development for e-mobility has a higher commercialization potential due to bigger target applicable market, higher performance and lower cost. …

Starting from 2020, Innolith is fully focused on the development of a 21700 energy cell for EVs and other e-mobility applications. Technically, it is a completely different cell – standard industry cylinder using state-of-the art materials and equipment vs old proprietary prismatic cell with thick foam based electrodes. The old ALEVO and newly developed I-State technologies are simply not comparable by performance, cost per kWh, sustainability and safety parameters. …

Innolith does not employ any members of the executive management team of ALEVO.

Sounds like interesting tech, could be a step in the right direction. Also Good to hear of a new technology that is ready now rather than in a few years time.

WIll be interesting to see if this is adopted by EV given the increase in ED Vs Current market. Plus should be interesting to EVTOl & Mining where safety is key...

Stephen Chalmers

Sounds like exactly what the EV industry has been crying out for - and if the lower costs of the cells translates into lower cost for the EVs ,then this will help accelerate the energy transition.

Also good to hear that the electrolyte is non-flammable; have been reading about too many battery fires recently.


Great to see a new battery technology come to the fore, particularly as the demand for EVs continues to grow. A reduction in the cost of the battery will only support the global adoption of EVs and ensure a clean energy transition is realistic

Ernesto Miller

Fantastic to see innovation in the EV battery space again!
A non-flammable model will make EV charging and transport much safer, hopefully this new tech will be available soon.
