Abstract
Disclosed is an electrolyte composition comprising an electrolyte salt, a monomer and an initiator that does not include any groups leading to gas formation during polymerization of the monomer. Also disclosed is an electrolyte composition comprising an electrolyte salt, a monomer and an initiator, wherein the electrolyte composition has a long shelf life. In one embodiment, the electrolyte composition has a viscosity of less than 1000 cP after it is stored 25° C. for 14 days. The disclosure further provides a polymer electrolyte synthesized from the electrolyte composition. In one embodiment, the polymer electrolyte is substantially free of visible bubbles. An electrochemical device comprising the same and preparation method therefor are also disclosed.
