摘要
Abstract
Capacity fading and the fine structure of electrode materials of a graphite/[Li(Ni0.4Co0.2Mn0.44)O2+LiMn2O4] battery during cycle were investigated. The experimental results reveal that the stability of crystal structure of Li(Ni0.4CO0.2Mn0.4)O2 is better than LiMn2O4 during cycle. The cycle performance of battery is related to the changing of the fine structure of electrode materials, including lattice parameter, crystallite size, micro-strain and stacking disorder.关键词
