BATTERY

The present disclosure relates to a technical filed of energy storage devices, and particularly relates to a battery. The battery includes an electrode assembly, a first tab, a second tab, a cap plate assembly, a first electrode terminal, a second electrode terminal and a shaping plate; the electrode assembly includes a first electrode plate, a second electrode plate and a separator arranged between the first electrode plate and the second electrode plate; each of the first electrode terminal and the second electrode terminal is arranged on the cap plate assembly; the first electrode terminal is connected to the first electrode plate through the first tab; the second electrode terminal is connected to the second electrode plate through the second tab; the shaping plate is arranged between the cap plate assembly and the electrode assembly, and each of the first tab and the second tab is bent around the shaping plate; the shaping plate is fixed and thermally fused to the cap plate assembly. The shaping plate is supported in the bent first tab and the bent second tab, which can prevent the first tab and the second tab from being inserted into an inside of the electrode assembly, so as to avoid the short circuit between the first tab and the second electrode plate and the short circuit between the second tab and the first electrode plate; therefore, the safety performance of the battery can be improved.
