Optimizing Ni-Rich LiNi₀.₈₅₋ₓCo₀.₀₄₊ₓTi₀.₁Al₀.₀₁O₂ Cathode Materials (x = 0.00 & 0.02) via Co-Precipitation for Lithium-Ion Batteries

Abstract

Lithium-ion batteries (LIBs) are widely used in electric vehicles and renewable energy storage systems due to their high energy density and long cycle life. Among key components, cathode materials critically influence battery performance. Nickel-rich compounds, such as LiNi₀.₈₅₋ₓCo₀.₀₄₊ₓTi₀.₁Al₀.₀₁O₂ (x = 0.00 and 0.02), have gained attention for their high energy storage capacity, improved thermal stability, and lower cost. This study focuses on synthesising and characterising these Ni-rich layered cathode materials via co-precipitation to examine how stoichiometric variation affects structural and morphological properties, with the aim of developing more efficient, stable, and durable batteries for future energy technologies.
