    摘要: A polymer solid electrolyte includes a crosslinked polymer or copolymer with a heterogenous or disordered polymer network synthesized from one or more crosslinkers, wherein at least one crosslinker has three or more polymerizable or crosslinkable terminals. In another embodiment, the crosslinked polymer or copolymer has a polymer network with topological defects. In one embodiment, the crosslinked polymer is not over-crosslinked. An electrochemical device with the crosslinked polymer or copolymer as electrolyte exhibits an improved electrochemical and safety performance. In certain embodiment, the crosslinkers include a) tri-acrylates, and tetra-acrylates; b) modified tri-acrylates and tetra-acrylates; c) silanes and siloxanes; and d) triazinane-triones.
