Abstract

A porous, hollow, microspherical composite of Li₂MnO₃ and LiMn_1/3Co_1/3Ni_1/3O₂ (composition: Li_1.2Mn_0.53Ni_0.13Co_0.13O₂) 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. [Figure not available: see fulltext.]
