Battery Materials Development

Our research focus lies in the development of novel, high-performance anode and cathode materials for the future, as well as the optimization of existing cell chemistries. Our team performs research on:

  • Generation 3, high-nickel NMC (LiNixMnyCo1-x-yO2) and LNMO (LiNi0.5Mn1.5O2) cathode materials
  • Si–C composites and Sn-based anode materials
  • Cathode and anode materials for Mg-ion batteries

Starting materials for the synthesis of cathode and anode materials
