Abstract

The invention discloses a battery module and belongs to the technical field of batteries. The battery module comprises a support and multiple batteries as well as a buffer structure, multiple batteries are arranged on the support side by side along the thickness direction of the batteries, the buffer structure comprises a patterned base, and the patterned base is formed by solidifying a liquid macromolecular material on the side surface of the batteries or on the support. The battery module provided by the invention has the advantages that the buffer structure is arranged on the side surface of the batteries or on the support, the buffer structure comprises the patterned base, and the patterned base is formed by solidifying the liquid macromolecular material; compared with the prior art, shock-resistant and dropping-resistant protection can be provided for the batteries and expansion and contraction of the batteries can be buffered, so that the batteries are avoided from being damagedwhen being collided, falling from a high place or being extruded; and materials can be obviously saved, so that production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] Lithium batteries are more and more widely used in our daily life. With different production processes and different usage requirements, lithium batteries have produced many different packaging forms, such as soft pack batteries, square batteries and cylindrical batteries. Among them, The housings of prismatic and cylindrical batteries are made of metal materials. [0003] For a prismatic battery module composed of prismatic batteries, in order to reliably assemble multiple prismatic batteries into groups, it is necessary to add an assembly and fixing structure outside. In order to protect each prismatic battery against shocks and drops, foam is usually pasted around the prismatic battery to form a buffer structure for protection. For pouch batteries, pouch batteries will expand and contract with charging and discharging, and ad...
