Abstract
The invention discloses a wedge-shaped stepped distributed porous lithium battery module, which relates to the technical field of lithium batteries, and is characterized in that it includes at least a plurality of single batteries, the outer wall of each single battery is wrapped with an insulating film, and the insulating film The outer wall is coated with a circle of colloid, which is located at the center of the side wall of the single battery; the porous bracket used to fix the single battery is provided with a plurality of circular mounting holes distributed in wedge-shaped steps on the porous bracket, and each installation The center of the inner wall of the hole has a groove along the circumference; the side wall of the porous bracket is provided with fastening screws and positioning pins; the single battery is inserted into the installation hole, and the colloid is located in the groove, and the single cell The battery is bonded to the porous support by colloid. By adopting the above technical solution, the present invention realizes the arrangement of as many single batteries as possible in a limited space, reduces the heat density of the module during operation, and improves the mechanical properties of the connection between the module and the whole battery pack.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a wedge-shaped stepped distributed porous lithium battery module. Background technique [0002] For mobile equipment or field operation equipment, power supply in emergency situations is a must. The lithium-ion battery pack can be used repeatedly for a long time as a recyclable backup power supply. At present, outdoor mobile devices have higher and higher requirements for power supplies, and are gradually developing in the direction of high power, high specific energy, light weight, and high reliability. [0003] Lithium battery module is an important part of the lithium battery pack, its space ratio, heat dissipation conduction rate, high specific energy and other indicators play a key role in the performance of the entire battery pack. [0004] There are two main methods for lithium battery modules: the upper and lower mold clamping method, and the bus bar welding a...
