Dendrite-free Li metal deposition in all-solid-state lithium sulfur batteries with polymer-in-salt polysiloxane electrolyte

Polymer-in-salt polysiloxane based composite solid electrolytes using cellulose acetate membranes as rigid frameworks are prepared by solution casting technique. The resultant electrolytes exhibit satisfactory ionic conductivities and mechanical properties simultaneously and could impede lithium dendrites and shuttle effect of polysulfides. The assembled batteries deliver high cycling performance, demonstrating a promising strategy for ambient temperature all-solid-state lithium sulfur batteries.291
