    • Improved cyclability of Nickel-rich layered oxides 

      Wagner, Nils Peter; Tolchard, Julian R; Tron, Artur; Pollen, Harald Norrud; Gaertner, Heiko; Vullum, Per Erik (Peer reviewed; Journal article, 2020)
      This study compares the physico- and electro- chemical properties of LiNi0.8Mn0.10Co0.1O2 (NMC811) and LiNi0.83Mn0.06Co0.09Al0.1O2 (NMCA) prepared by an oxalic acid co-precipitation. Deposition of a SiO2 surface coating ...

    • A Single-Pot Co-Precipitation Synthesis Route for Ni-Rich Layered Oxide Materials with High Cycling Stability 

      Pollen, Harald Norrud; Tolchard, Julian R; Svensson, Ann Mari; Wagner, Nils Peter (Peer reviewed; Journal article, 2022)
      In this work we report variations of LiNi0.88Mn0.06Co0.06O2 synthesised through a single-pot oxalic acid co-precipitation route, in which all cation precursors were added in the same step. The effects of Al-doping, ...
