Problems solved by technology

[0002] In the existing lithium battery pack (or lithium battery pack), several batteries are placed one by one in the corresponding packaging shell, and there is no filler between the batteries and the heat is dissipated directly through air convection. The heat dissipation efficiency of the lithium battery pack is low in use, and the temperature field in the lithium battery module shell is not uniform
And the copper-nickel composite sheet used to connect the individual batteries is exposed to the air, and it is prone to oxidation over time.
When a single battery in the battery pack module explodes, other batteries in the lithium battery module that cannot be controlled will not be affected, which can easily cause the failure of surrounding batteries or a series of explosions
In addition, there is no filler between the batteries and the batteries to isolate them, which is prone to loosening during use, especially when used in cars.

Abstract

The invention discloses a safety power lithium battery module. The safety power lithium battery module comprises a plurality of battery cores, corresponding compound current cut-off sheets and glue, wherein the plurality of battery cores are arranged in a lithium battery module shell; the glue is placed in the lithium battery module shell; and the glue is filled among the battery cores in the lithium battery module shell, or among the battery cores and into the corresponding compound current cut-off sheets in a pouring way. The lithium battery module is safe and reliable to use, and has stable performance and uniform heat dissipation.

Description

technical field [0001] The invention relates to a lithium battery. In particular, it relates to a safe power lithium battery module. Background technique [0002] In the existing lithium battery pack (or lithium battery pack), several batteries are placed one by one in the corresponding packaging shell, and there is no filler between the batteries and the heat is dissipated directly through air convection. The heat dissipation efficiency of the lithium battery pack is low in the state of use, and the temperature field in the lithium battery module housing is not uniform. Moreover, the copper-nickel composite sheet used to connect the individual batteries is exposed to the air, and it is prone to oxidation over a long period of time. When a single battery in the battery pack module explodes, other batteries in the lithium battery module that cannot be controlled will not be affected, which can easily cause the failure of surrounding batteries or a series of explosions. In ...
