A prominent sacrificing additive for lithium ion batteries is lithium squarates, which is typically incorporated via the cathode. However, gas is formed during their oxidation, which damages the cathode composite. To avoid this, a team from MEET Battery Research Center investigated whether lithium squarates can also be used as electrolyte additives. Read more
Replacing the environmentally harmful solvent N-methyl-2-pyrrolidone (NMP) in battery production with water is only possible in combination with a suitable, water-soluble binder like carboxymethyl cellulose (CMC). A MEET team has investigated how even small changes in the chemical structure of CMC influence the production and quality of cathodes. Read more
A key milestone has been reached in the FFB PreFab in Münster: The Fraunhofer Research Institution for Battery Cell Production FFB has produced its first electrically functional lithium ion battery cell. This marks the first time that a continuous process chain has been realized using exclusively European plant technology, from electrode production to charged cells. Read more
Lithium titanate suffers from significant gas evolution in the battery. A team from MEET Battery Research Center has investigated the influencing factors on this reaction in detail. Based on the results, the scientists analyzed previously unclarified aging mechanisms within the cells. Read more
