Abstract
The present disclosure discloses a lithium ion battery comprising a battery shell, a cover assembly, an electrode assembly, a first current collecting plate and a second current collecting plate. The electrode assembly comprises a positive plate, a negative plate and a separator provided therebetween which are coiled together. The electrode assembly and the current collecting plates are disposed in a space formed by the battery shell and the cover assembly. The first and second current collecting plates are disposed at each end of the electrode assembly respectively, with a first uncoated area of the positive plate and a second uncoated area of the negative plate being welded to the first and second current collecting plates respectively.
