Everything started back in 2021 when Lars Eriksson, Professor in Vehiclar Systems at Linköpings University, identified a great need in the battery industry to improve battery testing in battery R&D, production and test settings. Lars also concluded that EIS is the most advanced and interesting method for evaluating batteries and their chemistry. However, EIS, up until then, had been associated with one major drawback: that it was notoriously time consuming. A full scan of multiple frequencies could take hours if not days, depending on the information required.

Once the problem was identified, Lars set about finding a way to shorten EIS measurement times while preserving and/or improving data quality, resolution, reliability, repeatability etc. In truth, Lars exceeded beyond all expectations. With his discovery of R3 EIS single measurements can include up to 60 000 frequencies and take only a couple of minutes. Full State-of-Charge sweeps, on charge or discharge, are completed in only hours.

In order to take Lars’ invention to market the Batixt company was started in early 2023, together with Per Ohlin and Maria Murphy. 

Per, with his advanced knowledge in development and implementation of measurement instruments in industrial contexts and Maria with her background in business development and management, together with Lars who has a deep understanding of both batteries and EIS make up the highly skilled team required to bring such advanced technology to market.
