Solid polymer electrolytes (SPEs) with tunable network structures are prepared by a facile one-pot reaction of polyhedral oligomeric silsesquioxane and poly(ethylene glycol). These SPEs, with high conductivity and high modulus, exhibit superior resistance to lithium dendrite growth even at high current densities. Measurements of lithium metal batteries with a LiFePO4 cathode show excellent cycling stability and rate capability.
采用多面体低聚倍半硅氧烷和聚乙二醇的一锅法反应，制备了具有可调网络结构的固体聚合物电解质（SPE）。这些 SPE 具有高电导率和高模量，即使在高电流密度下，也表现出优异的抑制锂枝晶生长的能力。使用 LiFePO4 作为正极的锂金属电池的测量结果表明，其具有优异的循环稳定性和倍率性能。
