Problems solved by technology

The heat released by the battery during charging and discharging is very concentrated and difficult to dissipate, which will reduce the service life of the battery pack; in addition, once a single secondary lithium-ion battery in the battery pack encounters abnormal conditions such as high temperature, fire and explosion, it will directly Affect the single secondary lithium-ion battery around it, and then it is prone to continuous high-temperature fire and explosion, resulting in high-temperature fire and explosion of the entire battery pack in a short period of time; professional cameras and professional video lights using secondary lithium-ion battery packs Mobile devices such as mobile devices, movie film machines, and movie editing machines are in direct and close contact with the human body. Once the secondary lithium-ion battery pack used by it is exposed to high temperature fire and explosion, it may directly burn the human body and cause catastrophic accidents such as fire, which seriously threatens People's lives and property safety

Abstract

The invention discloses a lithium ion battery module with simple structure, high safety and good reliability, and a battery pack comprising the lithium ion battery module. The lithium ion battery module comprises monomer rechargeable lithium ion batteries (1) and a shell (2) made from a high-temperature resistant strong-toughness flame retardant material, wherein through holes (21) are formed between a front bottom surface and a back bottom surface of the shell (2) and are arranged in arrays, and each through hole is fixed provided with one of the monomer rechargeable lithium ion batteries (1). The lithium ion battery module and the battery pack can be widely applied to the field of power supplies.

Description

technical field [0001] The invention relates to a lithium ion battery module and a battery pack comprising the lithium ion battery module. Background technique [0002] The equipment used in news interview photography, movie shooting or TV drama shooting needs to be frequently moved due to the change of shooting scenes and angles, and the batteries used in them are also frequently moved. At present, most of the batteries used in these devices are lead-acid batteries. Lead-acid batteries Compared with lithium-ion batteries, the energy is lower and the density is higher. That is to say, compared with the same volume of lead-acid batteries and lithium-ion batteries, the energy of lead-acid batteries is much smaller but the weight is much larger. Because the equipment needs to be moved frequently, so The batteries used should not be too bulky. Restricted by factors such as weight, technical development maturity of lead-acid batteries and their capacity-to-mass ratio, the energy ...
