Abstract: The present invention generally relates to electrolytes for use in various electrochemical devices. In some cases, the electrolytes are relatively safe to use; for example, the electrolytes may be resistant to overheating, catching on fire, burning, exploding, etc. In some embodiments, such electrolytes may be useful for certain types of high-voltage cathode materials. In some cases, the electrolytes may include ion dissociation compounds that can dissociate tight ion pairs. Non-limiting examples of ion dissociation compounds include trialkyl phosphates, sulfones, or the like. Other aspects of the invention are generally directed to devices including such electrolytes, methods of making or using such electrolytes, kits including such electrolytes, or the like.

Abstract: A polymer electrolyte includes an additive and a crosslinked polymer with a heterogeneous polymer network synthesized from one or more crosslinkers, wherein at least one crosslinker has three or more polymerizable terminals. In another embodiment, the crosslinked polymer has a polymer network with topological defects. In some embodiments, the additive comprises element F and at least one of elements B and P. In some embodiments, the additive comprises F—B, F—P, F—P—O, F—P=O, or any combinations thereof. In one embodiment, the crosslinked polymer is not over-crosslinked. An electrochemical device with the crosslinked polymer as electrolyte exhibits an improved electrochemical and safety performance.
