Lithium Battery Research and Development (R&D)

- 3 minute read

R&D is a strategic function at TES, as we look to meet the demands of tomorrow, today. 

Taking an active role in research and development initiatives helps us to evolve our portfolio of services to proactively meet new challenges, in a way that embraces the opportunities presented by the Circular Economy, especially within the battery industry.  

Through innovation, we ensure that as the shift from combustion engines to electric vehicles (EVs) takes hold, that there are safe and compliant solutions for lithium car batteries that do not require mining more virgin materials. Through our processes today we already extract scarce and precious metals and commodities for use in new products, and through research and development, we are positioned to continually evolve and adapt in line with the needs of our customers and the sector. 


Started January 1st, 2021: (Anticipated to run for 3 years)

The German-funded project “accuRate”, which started at TES’s facility in Herten, features TES and two other consortium partners; LiPlus and the University of Munich, associated partners like VDE Renewables, two well-known German Automotive OEMs, and a Global insurance company. 

As the electric mobility and technology sector is experiencing a major boom, increasing numbers of e-vehicles on the road and more technology devices means that there are more lithium-ion batteries in use. However, to ensure that these batteries are economically and sustainably operated, the batteries’ state of health (SoH) needs to be better understood. 

Currently, recyclers, battery experts, automobile workshops, and secondary-market players do not have access to a critical part: a precise measurement of the batteries’ parameters, enabling an independent, objective, and reliable evaluation of their SoH. 

TES is testing the inner resistance of batteries, against several capacities and loading cycles. By understanding correlations in this data, will allow for the development of a rapid and single measurement, to understand that batteries overall State of Health (SoH). 

In the future, the ability to determine the remaining lifetime of a repurposed battery quickly and reliably will pave the road for more second-life battery applications,” said Thomas Holberg, Global Vice President, TES Sustainable Battery Solutions.  “Extending the lifetime of a battery will be a major contribution in reducing the overall carbon footprint of batteries before TES – as the final step - takes care of the recovery of the scarce materials in our recycling facilities.”


Burkhard Holder, Managing Director, VDE Renewables, said: It is only through reliable and well-proven methods of evaluating batteries’ SoH that will enable the certification of these batteries. This then builds a basis for greater market adoption and the improved bankability and insurability of batteries in second life applications.”


The development of this measurement will be a critical breakthrough in determining lifespans for EV batteries, extending lifespans, maintenance diagnostics, and more as batteries evolve. TES is in the perfect position to support this project given access to a wide variety and quantity of batteries from technology assets, but as importantly, is also well-positioned to help with the next stage of that battery once its SoH has been determined.
