Abstract

A porous, hollow, microspherical composite of Li2MnO3 and LiMn1/3Co1/3Ni1/3O2 (composition: Li1.2Mn0.53Ni0.13Co0.13O2) was prepared using hollow MnO2 as the sacrificial template. The resulting composite was found to be mesoporous; its pores were about 20 nm in diameter. It also delivered a reversible discharge capacity value of 220 mAh g(-1) at a specific current of 25 mA g(-1) with excellent cycling stability and a high rate capability. A discharge capacity of 100 mAh g(-1) was obtained for this composite at a specific current of 1000 mA g(-1). The high rate capability of this hollow microspherical composite can be attributed to its porous nature.
