Abstract
A battery includes a protective box provided with a guiding channel and a plurality of battery cells in the protective box. The plurality of battery cells include a first battery cell and a second battery cell adjacent to each other. The first battery cell includes a pressure relief end provided with a pressure relief mechanism. The pressure relief mechanism is configured to actuate release of internal pressure of the first battery cell in response to the internal pressure or an internal temperature of the first battery cell reaching a threshold. The guiding channel is configured to guide emissions released from the pressure relief mechanism. The pressure relief end of the first battery cell is staggered with one end of the second battery cell that is close to the pressure relief end, in a direction leaving the guiding channel.
