Ultra-high Capacity Li[Ni1/3Co1/3Mn1/3]O2 Cathode Synthesized Using a Novel MnO2 Template

Abstract

Abstract An ultra-high capacity Li[Ni1/3Co1/3Mn1/3]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.
