摘要/Abstract

摘要： 成功合成了一种新型锂离子电池正极材料—聚硫化冉酸(PSCA).固体核磁13C谱、FT-IR及电化学等测试表明,氯冉酸经过硫化之后,硫取代氯的位置而得到目标产物聚硫化冉酸(PSCA).在1.5～3.6V的电位区间内,以15mAh/g的电流密度作充放电测试,首次放电比容量高达287.6mAh/g,循环100圈后容量依然保持为169.9mAh/g.

关键词: 氯冉酸, 锂离子电池, 有机正极材料, 醌基基团

Abstract: A new organic cathode material,poly sulfurized chloranilic acid(PSCA),has been successfully synthesized for lithium-ion batteries. 13C solid state NMR and FTIR results indicated that the chorine in chronailic acid was substituted by sulfur after sulfurization. The electrochemical measurements showed that the initial discharge capacity of PSCA was up to 287.6 mAh/g,and 169.9 mAh/g still remained after 100 cycles when cycled between 1.5～3.6 V at the current density of 15 mA/g.

Key words: chloranilic acid, lithium-ion batteries, organic cathode material, quinone groups
