제목 Preparation of high performance LiFePO4 cathode materials manipulated by polyaniline
초록 The olivine-type cathode for lithium ion battery offers the thermally stable in fully charge/discharge state, environmental friendliness and inexpensiveness. LiFePO4 prepared by a milling technique has a limitation in improving electrochemical performance because of its low electrical conductivity and the morphological weakness. LiFePO4 was coated by polyaliline as carbon precursor. The polyaniline plays an important role as an agent in making core/shell structure related to the decreased particle size, and makes electronic conductivity improve. The electrochemical performance of LiFePO4 coated with polyaniline was better than LiFePO4.
