准固态锂离子电池正极材料柱[5]醌的研究
摘要
Organic electrode compounds have been considered as potential cathode material for lithium ion batteries owing to their advantages including high capacity, low cost and resource renewability. However, the application of organic electrode materials is hindered by their severe solubility in liquid organic electrolyte. Herein, the quasi-solid-state lithium-ion batteries have been successfully constructed by using poly(methyl acrylate)/ poly(ethylene glycol) (PMA/PEG) quasi-solid electrolyte and pillar[5]quinone cathode material for the first time. As a result, the pillar[5]quinone material provided an initial discharge capacity of 410 mA h/g and a capacity retention of 88.5% after 100 cycles at 0.2 C, which shows the pillar[5] quinone potential applications for high energy quasi-solid-state lithium-ion batteries.
