The recycling of lithium ion batteries is essential to achieve a circular economy. Using water during the mechanical treatment is under investigation. A MEET team has developed a method that can be used to precisely determine organic electrolyte residues in aqueous samples. Read more
The solvent N-methyl-2-pyrrolidone (NMP) is currently required to produce positive electrodes (cathodes) for lithium ion batteries. With the aim of replacing NMP as a solvent without compromising the performance of the battery cells, a team from MEET Battery Research Center has compared potential alternatives for cathode production.

In a joint study, MEET Battery Research Center and the Institute of Physical Chemistry at the University of Münster as well as Helmholtz Institute Münster have examined silicon/graphite composite anodes in detail. The team discovered that the material stress of silicon cannot yet be minimized in long term – even if the material is only added to the graphite anode in small amounts. Read more
The potential of solid-state batteries is enormous. However, they can only reach technological and market readiness if all mechanisms inside the cells are precisely understood. A team from MEET Battery Research Center and the American Lawrence Berkeley National Laboratory has investigated the reaction mechanisms at the interphases between the solid electrolyte and the electrode in detail.
