Problems solved by technology

However, due to the thinner metal foil for pressure relief, perforation is prone to occur during laser welding. Therefore, the use of the above-mentioned explosion-proof structure of the battery results in time-consuming and labor-intensive preparation of the battery, and it is easy to cause liquid leakage, low product yield, or affect the explosion-proof pressure. value control

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] figure 1 A self-alarm explosion-proof graphene battery pack according to an embodiment of the present invention is schematically shown. As shown in the figure, the self-alarm explosion-proof graphene battery pack includes a casing 1 and a battery cell 2 .

[0026] Wherein, a cavity is provided inside the casing 1, and a plurality of protruding strips 11 are provided on the inner wall of the casing 1. The strips 11 have deformation parts 111, and the electric core 2 is accommodated in the cavity. The electric core 2 and at least one The bodies 11 are in contact so that the deformation portion 111 of the strip body 11 is deformed. Thus, by arranging several strips 11 on the inner wall of the housing 1, and the electric core 2 is in contact with at least one of the strips 11 so that the deformation part 111 of the strip 11 is deformed, the electric core...

Abstract

The invention discloses a self-alarm explosion-proof graphene battery pack. The self-alarm explosion-proof graphene battery pack comprises a shell and battery cells, wherein a cavity is formed in theshell, a plurality of convex strip bodies are arranged on the inner wall of the shell, and each strip body is provided with a deformation part; a positive terminal and a negative terminal are arrangedon the shell; the battery cell is accommodated in the cavity and is in contact with the at least one strip body to enable the deformation part of the strip body to deform; the battery cell comprisesa positive electrode, a negative electrode and a diaphragm, the diaphragm is positioned between the positive electrode and the negative electrode, and a graphene material is arranged on the negative electrode; the positive electrode is connected with a positive tab, the positive tab is connected with a positive binding post, the negative electrode is connected with a negative tab, and the negativetab is connected with a negative binding post; the shell is provided with an explosion-proof structure, and the explosion-proof structure comprises a groove formed in the top surface or the side surface of the shell. The charging pile has the advantages of being high in safety performance, fast in charging and high in bearing capacity.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a self-alarming explosion-proof graphene battery pack. Background technique [0002] Lithium battery is a battery using metallic lithium or its compounds. Metal lithium or its compounds are used in the positive electrode, negative electrode or electrolyte of the battery. It has a high storage energy density, which has reached 460-600Wh / kg, which is about the same as that of lead-acid batteries. 6-7 times; Lithium batteries usually include lithium metal batteries and lithium ion batteries. With the development of microelectronics technology, miniaturized equipment is increasing day by day, which puts forward high requirements on power supply, and lithium battery has entered a large-scale practical stage. [0003] During the charging and discharging process of the lithium battery, when the battery heats up, part of the gas generated during the activation process inside the batte...
