Porous, hollow Li1.2Mn0.53Ni0.13Co0.13O2 microspheres as a positive electrode material for Li-ion batteries

A porous, hollow, microspherical composite of Li 2 MnO 3 and LiMn 1/3 Co 1/3 Ni 1/3 O 2 (composition: Li 1.2 Mn 0.53 Ni 0.13 Co 0.13 O 2 ) was prepared using hollow MnO 2 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. Graphical Abstract ᅟ
