摘要
利用一种Ti_(x)O_(y)-Ti_(3)C_(2)异质结构材料对电池隔膜进行改性,以有效地控制锂硫电池中存在的穿梭效应,并提高作为正极活性物质硫的利用率.利用简单的涂覆法将Ti_(x)O_(y)-Ti_(3)C_(2)修饰在PP隔膜表面,制备成复合隔膜.采用结构表征及电池性能测试对其进行研究.结果表明,相比较于常用的氧化石墨烯修饰的隔膜,经过Ti_(x)O_(y)-Ti_(3)C_(2)改性后的隔膜材料化学稳定性能显著,同时更能有效遏制穿梭效应.
A heterostructure material Ti_(x)O_(y)-Ti_(3)C_(2)was used to modify the membrane of the lithium-sulfur(Li-S)battery,so as to effectively control the shuttle effect and improve the utilization of sulfur.The final synthesized Ti_(x)O_(y)-Ti_(3)C_(2)heterojunction material is used to modify the PP membranes.The structure characterization and battery performance tests were used to study the membrane,and the results showed that compared with the commonly used oxide graphene modified membrane,the membrane material modified by Ti_(x)O_(y)-Ti_(3)C_(2)had significant chemical stability and and can effectively suppress the shuttle effect in Li-S battery.
