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.

High-voltage lithium ion batteries are characterized by high energy and power densities, but often suffer from a shorter lifetime. A team from MEET Battery Research Center and the Institute for Plant Biology and Biotechnology at the University of Münster has now investigated how a bio-based electrolyte additive influences the lifetime of these battery cells.

A team from MEET Battery Research Center, Helmholtz Institute Münster, and the South Korean company LG Energy Solution has investigated the influence of synthesis and calcination parameters on the discharge capacity and cycle stability of cathodes made of lithium-manganese-rich layered oxide.

Nickel-rich cathodes enable high energy density in lithium ion batteries, but they rely on the critical material cobalt to remain structurally stable. An international research collaboration has now demonstrated that cathodes for high-performance lithium ion batteries can be produced using titanium instead of cobalt while still remaining stable over many charging cycles.
