Popis:	The layered lithium-manganese oxide () as a cathode material of lithium ion secondary batteries was prepared and characterized the physico-chemical and electrochemical properties. The morphological and structural changes of MnO(OH) and are closely connected to the changes of electrochemical properties. The crystallinity of is enhanced as the annealing temperature increase, but its capacity is reduced due to the easier structural changes of less crystalline than highly crystalline one. Moreover, the addition of buffer material such as MnO(OH) into cathode causes to reduce the morphological and structural changes of layered and increase the discharge capacity and cycleability.
