Abstract
Solid polymer electrolytes (SPEs) with tunable network structures are prepared by a facile one-pot reaction of polyhedral oligomeric silsesquioxane (POSS) and poly(ethylene glycol) (PEG). These SPEs with high conductivity and high modulus exhibit superior lithium dendrite growth resistance even at high current densities. Measurements of lithium metal batteries with a LiFePO4 cathode show excellent cycling stability and rate capability. Also disclosed are products made by the process of the invention and batteries including such products.
