The Influence of Particle Characteristic of Manganese Dioxide on Performance of Spinel Lithium Manganese Oxide

Abstract:

Several kinds of chemical manganese dioxide with different particle characteristic were prepared by redox reaction in liquid phase. Then, spinel lithium manganese oxide was synthesized by liquid impregnation. The result implied that the influence of particle characteristic on test result is important. The spinel lithium manganese oxide prepared by spherical MnO₂ has better cycle performance than the spinel lithium manganese oxide prepared by MnO₂ with irregular shape .The spinel lithium manganese oxide with little particle size has high initial specific capacity. The spinel lithium manganese oxide prepared by MnO₂ with anemone shape has high specific capacity and stable cycle performance.
