Abstract
The present application relates to a battery, an electrical device, a method and a device for manufacturing the battery, wherein the battery includes: a plurality of battery cells, and the plurality of battery cells are configured to be electrically connected through a bus component; the battery cells include a pressure relief mechanism , the pressure relief mechanism is used to actuate to release the internal pressure when the internal pressure or temperature of the battery cell reaches a threshold value; the insulating part is used to cover the confluence part to prevent discharge from the battery cell when the pressure relief mechanism is actuated objects short circuit at least one battery cell. Covering the confluence part with an insulating part can prevent some of the discharge from being released from one or some faulty battery cells from splashing on conductive objects such as the confluence part, thereby reducing the occurrence of short circuits or Probability of high voltage ignition.
Description
technical field [0001] The present application relates to the technical field of batteries, in particular to a battery, an electrical device, a method and a device for preparing a battery. Background technique [0002] In recent years, the emergence of new energy vehicles has played a huge role in promoting social development and environmental protection. As an important new power source, batteries are widely used in the field of new energy vehicles. [0003] At present, thermal runaway and spontaneous combustion of batteries during use is a major factor causing safety accidents of new energy vehicles. When a certain battery cell in the battery undergoes thermal runaway, high-temperature emissions will be ejected from the battery cell, and the high-temperature discharge will splash to surrounding battery cells, causing serious safety accidents. Contents of the invention [0004] The present application provides a battery, an electrical device, a method and a device for ma...
