Battery, apparatus using battery, and preparation method and preparation device of battery

A battery comprising:

• a protective box provided with a first guiding channel and a second guiding channel;
• and
• a plurality of battery cells stacked in the protective box in a stacking direction and each having a height direction and a width direction perpendicular to each other and both perpendicular to the stacking direction, the plurality of battery cells including:
• a first battery cell including a terminal end and a non-terminal end opposite each other in the height direction, a positive electrode terminal and a negative electrode terminal of the first battery cell being provided at the terminal end of the first battery cell, the non-terminal end of the first battery cell having no electrode terminal, one of the terminal end and the non-terminal end being a pressure relief end in the height direction, the pressure relief end being provided with a first pressure relief mechanism, and the first pressure relief mechanism being 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;
• and
• a second battery cell adjacent to the first battery cell and including a terminal end and a non-terminal end opposite each other in the height direction, a positive electrode terminal and a negative electrode terminal of the second battery cell being provided at the terminal end of the second battery cell, the non-terminal end of the second battery cell having no electrode terminal, the second battery cell including a pressure relief side in the width direction, the pressure relief side being provided with a second pressure relief mechanism, and the second pressure relief mechanism being configured to actuate release of internal pressure of the second battery cell in response to the internal pressure or an internal temperature of the second battery cell reaching the threshold;
• wherein:
• the first guiding channel is configured to guide emissions released from the first pressure relief mechanism, and the second guiding channel is configured to guide emissions released from the second pressure relief mechanism;
• and
• 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 first guiding channel, and the pressure relief side of the second battery cell is staggered with one side of the first battery cell that is close to the pressure relief side, in a direction leaving the second guiding channel, wherein:
• the pressure relief end of the first battery cell is the terminal end of the first battery cell and the one end of the second battery cell that is close to the pressure relief end is the terminal end of the second battery cell;
• or
• the pressure relief end of the first battery cell is the non-terminal end of the first battery cell and the one end of the second battery cell that is close to the pressure relief end is the non-terminal end of the second battery cell.
