摘　　要：硅烷添加剂因具有高热稳定性、低可燃性、无毒性、高电导率和高分解电压等优点,近年来成为了锂离子电池电解液新型添加剂的研究热点。本文重点介绍了在硅烷电解液添加剂中Si—O结构、Si—N结构所发挥的作用以及机理,最后对硅烷添加剂的进一步研究趋势和应用前景进行了展望。Silane additives have attracted recent attention as novel electrolytes for lithium-ion batteries due to their high thermal stability, low flammability, non-toxicity, high conductivity and high decomposition voltage. The role and mechanism of Si—O and Si—N structure in silane electrolyte additives were mainly reviewed. In addition, the further research trends and application prospects of silane additives were also prospected.
