Abstract

A battery (100) and an electrical device, relating to the field of batteries. The battery (100) comprises battery cells (20) and a support member (30). Each battery cell (20) comprises a housing (21) and a pressure relief component (212). The housing (21) comprises a first wall portion (211), and the pressure relief component (212) is provided on the first wall portion (211). The pressure relief component (212) comprises a first groove (2121), and is configured to crack along the first groove (2121) during pressure relief of the battery cell (20). The support member (30) supports the first wall portion (211). The support member (30) has a support surface (31) facing the first wall portion (211), and the support surface (31) is provided with a clearance portion (32). In the direction of thickness of the first wall portion (211), a projection of the first groove (2121) lies within the clearance portion (32). By providing the clearance portion (32) on the support member (30) and by allowing the projection of the first groove (2121) in the direction of thickness of the first wall portion (211) to lie within the clearance portion (32), the clearance portion (32) can provide clearance for the first groove (2121). Thus, during pressure relief of the battery cell (20), the support member (30) is less likely to abut against the outer side of the first groove (2121), reducing the likelihood of suppressing the cracking of the first groove (2121). This arrangement ensures that the first groove (2121) can crack promptly during pressure relief of the battery cell (20), thereby helping to improve the reliability of the battery (100).
