摘要

Here we introduce a new synthetic approach to grow polyacetonitrile (PAcN) oligomer viaelectrochemical method, and the polymerization degree of PAcN oligomer is investigated completelyby mass spectrum. The PAcN oligomer with well-defined polymerization degree is obtained in thiswork, which shows an excellent heat resistance till 400 Particularly, the PAcN oligomer issuccessfully applied as an additive of the solid polymer electrolyte for lithium batteries. By adding 3wt. % PAcN oligomer, the ionic conductivity of the PEO-based SPE grows by two orders ofmagnitude and reaches 2.5910 S/cm at 30 Furthermore, the electrochemical stability windowand mechanical processing property of SPE are also enhanced greatly by adding of PAcN oligomer.The PAcN oligomer is proved to be a promising additive for SPE.
