Abstract
A lithium battery and a method for fabricating the same are provided. The lithium battery includes an anode, a cathode located opposite to the anode, a separator and an electrolyte solution. The separator is located between the anode and the cathode, wherein the anode, the cathode and the separator commonly define a containing region. The electrolyte solution is located in the containing region, and includes an organic solvent, a lithium salt and an additive. The additive includes a maleimide-based compound and a hydroxyl-containing species having a molecular weight less than 1000, and a content of the hydroxyl-containing species in the electrolyte solution ranges between 0.05 wt % and 5 wt %. The lithium battery and the fabrication method thereof can solve problems of water contained in the battery, and an environment with high dryness and low moisture content is unnecessary for fabrication, thereby reducing the production cost and enhancing the battery performance.
