锂离子电池用磷基负极材料的嵌脱锂机理
Lithium intercalation/deintercalation mechanism of phosphorus based anode material for Li-ion battery
摘要
Abstract
Based on first-principle plane wave pseudopotential method,the lithium intercalation/deintercalation mechanism of phosphide with different lattice structure as anode materials was investigated.The P-3 whose space group was CMCA was the best one among the three phosphide phases,whose volume expansion ratio of the lithium rich state(Li2P) was only 35.89%,with theoretical specific capacity of 1 729 mAh/g,which showed the value of being a substitute for carbon anode.The lithium intercalation potential of the three phosphide phases was high,with poor electrical conductivity.关键词
