Synthesis of Micron-Sized LiNi0.8Co0.1Mn0.1O2 and Its Application in Bimodal Distributed High Energy Density Li-Ion Battery Cathodes

The uniform and smaller-sized (~3 ?m) LiNi0.8Co0.1Mn0.1O2 (SNCM) particles are prepared via a fast nucleation process of oxalate co-precipitation, followed by two-step calcination procedure. It is found that the vigorous agitation enables us to produce nuclei having size which then grow into micron-particles in less than few minutes. impacts solution pH, precipitation time, temperature, surface modification with ZrO2 on structural, morphological, electrochemical properties SNCM systematically examined identify optimal synthetic conditions. A novel bimodal cathode design has been highlighted using combination conventional large (~10 LiNi0.83Co0.12Mn0.05O2 (LNCM) achieve high volumetric energy density cathode. discharge capacity be 526.6 mAh/cm3 for L80% + S20%, whereas only 480.3 360.6 L100% S100% unimodal, respectively. Moreover, bi-modal delivered higher specific (622.4 Wh/kg) (1622.6 Wh/L) unimodal (596.1 Wh/kg 1402.1 after 100th cycle. This study points promising utility material Li-ion battery applications.
