Ultra-high Capacity Li[Ni1/3Co1/3Mn1/3]O2Cathode Synthesized Using a Novel MnO2Template

Abstract

An ultra-high capacity Li[Ni_1/3Co_1/3Mn_1/3]O₂ (T-LNCM) cathode material was synthesized using a novel MnO₂ template comprising nanorods of 114 nm diameter, which increased the surface area of the material to 3.19 m² g⁻¹. Owing to its large surface area and high lithium diffusion coefficient (4.72 × 10⁻¹⁴ cm² s⁻¹), T-LNCM exhibits an ultra-high capacity of 220.2 mAh g⁻¹ at 0.1 C. The capacity of T-LNCM is significantly higher than that of the conventional LNCM cathode material.
