High Ionic Conductivity of Composite Solid Polymer Electrolyte via In Situ Synthesis of Monodispersed SiO2 Nanospheres in Poly(ethylene oxide).
TL;DR: Much stronger chemical/mechanical interactions between monodispersed 12 nm diameter SiO2 nanospheres and poly(ethylene oxide) (PEO) chains were produced by in situ hydrolysis, which significantly suppresses the crystallization of PEO and thus facilitates polymer segmental motion for ionic conduction.

Suppression of lithium dendrite growth using cross-linked polyethylene/poly(ethylene oxide) electrolytes: a new approach for practical lithium-metal polymer batteries.
TL;DR: The results suggest that a high-modulus SPE is not a requirement for the control of dendrite proliferation, and a cross-linked polyethylene/poly(ethylene oxide) SPE with both high ionic conductivity and excellent resistance to dendrites growth is reported.
