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.

The electrolyte solvent acetonitrile is particularly suitable for lithium ion batteries that are designed for fast charging and low temperature applications. Acetonitrile can decompose before a sufficiently protective solid electrolyte interphase (SEI) has formed. Researchers have therefore investigated how the electrolyte additive vinylene carbonate can contribute to the formation of a sufficient SEI. Read more
A team from MEET Battery Research Center has investigated various electrolyte formulations for batteries used in high-voltage applications. The scientists combined different concentrations of fluoroethylene carbonate (FEC) with lithium difluorophosphate (DFP) and then conducted long-term cycling tests. Read more
