Abstract

A novel architecture, one-dimensional, microrod-like Ni-rich LiNi0.8Co0.1Mn0.1O2 cathodes assembled from small primary particles have been successfully constructed through morphology-conserved and solid-phase lithium implantation reaction. The considerable initial reversible discharge capacity (198.5 mAh·g−1 at 0.2 C) and cyclic performance (capacity retention of ∼73% after 100 cycles at 1 C) are obtained, attributed to the combined merits of unique microrod-like porous structure. Moreover, this work can be regarded as an attractive synthetic pathway toward the development of high-performance Ni-rich battery materials in future.
