【 摘 要 】

In this paper we report the synthesis of a new kind of single ion conductor based on a new lithium salt, lithium bis(allylmalonato)borate (LiBAMB), and an allyl group containing comb branch polyacrylate ether. Since LiBAMB has allyl groups on both sides, after connection to the polymer chain through tetramethyldisiloxane by hydrosilylation it not only acts as a lithium source but also acts as a cross-linking site to enhance the mechanical properties of the resulting new single ion conductors. Plasticizers such as mixtures of PC, EC, DMC and TEGDME were used to obtain the corresponding gel single ion conductors.
