摘　　要：聚硅氧烷(PS)因较低玻璃化温度(T_(g)<-100℃),良好的耐热性、优异的离子电导率和电化学稳定性,以及分子结构设计多样化等特点,在固态电解质领域具有巨大的应用潜力。尽管已有大量PS固态电解质的研究报道,但仍然面临着一些挑战,难以满足实际应用的要求。介绍了目前PS聚合物固态电解质的现状,主要包括优缺点与性能要求,从化学改性和物理改性两个方面阐述了改性策略,总结PS聚合物基固态电解质的改性方法,并分析了未来的发展趋势。Polysiloxane has shown great potential in the field of solid electrolytes due to its low glass transition temperature(T_(g)<-100℃),excellent heat resistance,high ionic conductivity and perfect electrochemical stability,as well as various molecular structure design.Although great efforts have been made in this field,polysiloxane-based electrolytes still face huge challenges,which hinder their practical application.In this paper,we have presented the current status of polysiloxane-based polymer solid electrolytes,including their advantages,disadvantages,and performance requirements.Then,the modification strategies were described from the perspectives of chemical modification and physical modification.In the end,the modification methods of polysiloxane polymer solid electrolyte were summarized,and its future development trend was prospected.
