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 LiFePO 4 cathode show excellent cycling stability and rate capability.
