Problems solved by technology
However, the thermal conductivity of the thermal pad or thermal paste is relatively low, resulting in less efficient cooling of the battery
Moreover, the heat conduction pad or heat conduction glue has the risk of aging and failure, which affects the consistency of heat conduction, resulting in accelerated decay of the life of the battery module

The invention discloses a battery, a battery module with the same, a power battery pack and an electric vehicle. The battery comprises: a pole core; and a shell comprising a battery shell and a cooling shell, wherein the pole core is packaged in the battery shell, the cooling shell is connected to the battery shell, and a cooling cavity is defined in the cooling shell. According to the battery disclosed by the invention, the shell comprises the battery shell and the cooling shell, the cooling shell is connected to the battery shell, and the cooling cavity is defined in the cooling shell, so that a cooling liquid can be in direct contact with the battery shell, the heat conduction efficiency is improved, the performance of the battery can be improved, and the service life of the battery is prolonged. Moreover, the battery arranged in this way does not need middle heat conduction materials such as a heat conduction pad or heat conduction glue, so that the cost of the whole battery can be reduced.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery and a battery module, a power battery pack, and an electric vehicle. Background technique [0002] The working current of the battery module is large, and the heat generation is large. At the same time, because the battery module is in a relatively closed environment, the temperature of the battery will rise. Therefore, liquid cooling tubes are usually used to dissipate heat from the battery of the battery module. [0003] In the related art, the liquid cooling tube needs to be in contact with the battery to realize heat dissipation of the battery. In order to ensure full contact between the liquid cooling tube and the battery, it is necessary to add a thermal pad or thermal conductive glue between the battery module and the liquid cooling tube. However, thermal pads or thermal pastes have relatively low thermal conductivity, resulting in inefficient cooling of the b...
