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.

Abstract: The present invention relates to liquid crystal elastomers having two-way shape memory effect and methods of making such LCEs. The method of preparation includes the steps of polymerizing at least two monomers with crosslinking polymer, prealigning the resultant polymer, crosslinking the resultant polymer, and preparing the liquid crystal elastomer. The liquid crystal elastomer can be drawn to fibers.
