LITHIUM BATTERY

摘要

Disclosed is a lithium battery including an anode, a cathode, and a polymer gel electrolyte contacting the anode, in which the ion conductivity of the polymer gel electrolyte is 10-3 S/cm or greater, the lithium ion transfer rate is 0.15 or greater, the lithium ion mobility is 10-6 cm2/V·sec or greater, and the polymer gel electrolyte includes a lithium salt, a polymer of capable of forming a composite with the lithium salt, an insulating inorganic filler, and an organic solvent, wherein the organic solvent is inactive with respect to lithium, an anion radius of the lithium salt is 2.5 angstrom or greater, and a molecular weight of the lithium salt is 145 or greater.
