The range of materials for investigation in this study was chosen to provide insights into the effect of LMFP Mn content on olivine phosphate electrode characteristics, including up to a challenging but advantageous Mn content of 80 %. The inclusion of the LMFP/NMC blend material is reflective of recent interest in taking advantage of the unique combined characteristics. To accurately reflect current industry status, all materials were commercially obtained and are available in large quantities. Firstly, the morphology of the active materials was studied. The choice of appropriate morphology is heavily dependent on the characteristics of the material in question, with both particle size and crystalline domain size (single-crystal vs polycrystalline) varying with material and manufacturer. Figure shows SEM images of the phosphate and blend cathode material powders examined in this study.
