Problems solved by technology

[0005] From the perspective of technical theory, the lithium iron phosphate battery has a small improvement in the danger of fire and explosion of the battery, but it is not thorough, and the danger is equally prominent.
[0006] Under various circumstances, the battery may be dangerous due to external short circuit, internal short circuit, and overcharge.

Embodiment Construction

[0056] like Figure 1 to Figure 15 As shown, for existing defects, the subject of protection of the present invention is as follows:

[0057] The development is a lithium battery power battery assembly. There are two situations in the installation process of the existing cylindrical lithium battery. One is to directly bundle membrane materials to form a power battery pack. The power battery pack exists The problem is that it is easy to accumulate heat, causing temperature rise, self-expansion, liquid leakage, spontaneous combustion, self-explosion, and poor safety. To solve this problem, the existing solution is to add a frame. The existing frame has thermal expansion and contraction. The phenomenon is still obvious. For example, the solution disclosed in the Chinese patent CN204927374U, in which the support adopts injection molded parts, has the functions of insulation and positioning, and can facilitate the assembly of cylindrical lithium batteries. There is no fundamental ...

Abstract

The invention discloses a light-weight safe battery cell support, and a power battery pack. According to the light-weight safe battery cell support, a support main body is a noncombustible foamed block prepared from a macromolecule resin, a foaming agent, glass fiber, and stone powder via chemical foaming, air holes of the noncombustible foamed block formed after foaming are filled with inert gas such as carbon dioxide, nitrogen gas, and ammonia gas; first circular holes are uniformly distributed in the support main body, the support main body is penetrated by the first circular holes from top to bottom, and the first circular holes are formed in shaping process of the support main body. The core parts of the light-weight safe battery cell support comprise the support main body; the light-weight safe battery cell support is prepared via foaming of organic resins, is light, and can be recycled effectively; and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a lightweight battery cell support and a power battery pack. Background technique [0002] At present, lithium-ion power batteries are popular in my country, and lithium iron phosphate batteries refer to lithium-ion batteries that use lithium iron phosphate as the positive electrode material. [0003] There are many kinds of positive electrode materials for lithium-ion batteries, mainly including lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobaltate is currently the positive electrode material used in most lithium-ion batteries, while other positive electrode materials have not been mass-produced in the market due to various reasons. Lithium iron phosphate is also one of the lithium-ion batteries. In terms of the principle of materials, lithium iron phosphate is also an intercal...
