Abstract
Disclosed is a battery, including a shell assembly, a jellyroll, and a support bar. The shell assembly defines a receiving cavity. The jellyroll is received in the receiving cavity. The support bar is disposed at a middle portion of the jellyroll. Two ends of the support bar protrude to an outside of the jellyroll and abuts against two opposite inner walls of the shell assembly. Positions of the shell assembly abutted by the support bar are recessed to form positioning slots. The two ends of the support bar are inserted into the positioning slots. The shell assembly includes a shell and a cap set connected to the shell. The shell defines an opening, the cap set covers and seals the opening. At least one end of the support bar abuts against the cap set.
