(395f) Co-Precipitation of NMC Cathode Material for Rechargeable Li-Ion Batteries.

Lithium-ion batteries are the ideal energy storage device as they have high energy and power density as well as having high energy efficiency.^1,2 As a result, they have multiple applications such as electric vehicles, portable electronics like cellphones and laptops and applications in power grid systems for renewable energy from solar and wind sources.^1,3,4 Layered oxides such as nickel manganese cobalt (NMC) oxides are the most promising cathode materials for lithium-ion battery systems as they have high reversible capacity and relatively low cost.^1,2,5 Literature reported that the morphology of these cathode materials is important as it can affect the electrochemical performance of the battery.⁶ This presentation will elaborate on the following topics: (1) The effect of different synthetic parameters on the morphology of the NMC cathode material, including pH, residence time, ligand concentration, calcination condition, etc. and (2) The influence of morphology on the battery performance. Morphology will focus on both the primary and secondary particles.
