Abstract
The embodiments of the present application relate to batteries, electrical equipment, methods and equipment for preparing batteries. The battery includes: adjacent first battery cells and second battery cells, the first battery cell includes a pressure relief mechanism, the pressure relief mechanism is arranged on the first wall of the first battery cell, the pressure relief mechanism The pressure mechanism is used to actuate to release the internal pressure when the internal pressure or temperature of the first battery cell reaches a threshold value; the fire-fighting pipeline is used to accommodate the fire-fighting medium, and the fire-fighting pipeline is used to actuate the pressure relief mechanism The fire-fighting medium is discharged toward the first wall; the blocking part protrudes from the first wall along the first direction, and the first direction is a direction perpendicular to the first wall. The expelled fire fighting medium flows from the first battery cell to the second battery cell. The battery, electrical equipment, method and equipment for preparing the battery in the embodiments of the present application can improve the safety performance of the battery.
Description
technical field [0001] The present application relates to the field of energy storage devices, in particular to batteries, electrical equipment, methods and equipment for preparing batteries. Background technique [0002] Energy saving and emission reduction is the key to the sustainable development of the automobile industry. In this case, electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy saving and environmental protection. For electric vehicles, battery technology is an important factor related to its development. [0003] In the development of battery technology, in addition to improving the performance of batteries, safety issues are also a problem that cannot be ignored. If the safety of the battery cannot be guaranteed, the battery cannot be used. Therefore, how to enhance the safety of batteries is a technical problem to be solved urgently in battery technology.
