New battery materials are typically first tested in coin cells. However, they age considerably faster than pouch cells. To identify the causes of this format dependent aging, a team from MEET Battery Research Center subjected coin cells and pouch cells containing identical materials to cyclic and calendar aging and compared the results.

How can high-performance solid-state batteries based on lithium and sodium be developed? This is the central question being addressed by the Franco-German research project “HiPoBat – High Power Batteries”. On 20 and 21 October, around 75 researchers and other project participants gathered in Münster to discuss the latest results and define the next steps for the third and final year of the project.

A potato, combined with a few components – and immediately a small diode lights up. 40 young researchers explored how this works during the “The Mouse's Open Doors Day” event at MEET Battery Research Center on October 3. Together with MEET scientists Dr Philip Niehoff and Felix Dahlhaus, the children built their own potato batteries and discovered how a chemical reaction generates electric current. Read more
A promising approach to reduce the N-methylpyrrolidone content – and thereby lowering energy consumption in the existing manufacturing process – is to modify the properties of the binder polyvinylidene difluoride (PVdF). The MEET team has therefore investigated how the molecular weight of PVdF influences the properties of the electrode paste and the composite electrode, as well as the electrochemical performance of the cathodes.
