Problems solved by technology

[0003] 1. The liquid injection port is open during the formation process, and the release of toxic gas generated during the formation process into the air will cause certain environmental pollution;
[0004] 2. Due to the large amount of gas produced during the formation process of the battery case, the internal pressure of the battery case will increase, making it easier to bulge;
[0005] 3. When the lithium-ion battery discharges gas, it cannot discharge the excess electrolyte inside the battery in time, so it is prone to electrolyte residue;
[0006] 4. The formation is not sufficient, and there is still room for improvement in the uniformity, stability and compactness of the SEI (solid electrolyte boundary membrane) film

Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the examples.

[0034] Such as Figure 1-2 As shown, a new type of bed-of-needles probe module includes a base plate 101. The probe assembly 102 is composed of a pair of positive probes 1021 and negative probes 1022 fixed on the base plate 101 at intervals. The positive probe 1021 and the negative probe 1022 needles pass through the bottom plate 101 and are located directly above the positive pole 803 and negative pole 804 of the lithium battery (802) below the bottom of the bottom plate 101, and the upper part of the bottom plate 101 is located on both sides of the positive probe 1021 and the negative probe 1022. 109, the upper part of the bottom plate 101 is located at one end of the positive electrode probe 1021 and the negative electrode probe 1022 ( figure 1 A rear...

Abstract

The invention relates to a novel formation needle bed probe module, which comprises a baseplate (101). A negative pressure device is disposed between a positive probe (1021) and a negative probe (1022) above the baseplate (101), the negative pressure device passes through the baseplate (101) and is located right above a lithium battery (802) liquid injection port (805) below the baseplate (101) bottom, the negative pressure device seals the liquid injection port (805) to form a negative pressure system. According to the invention, the liquid injection port is sealed in the formation process to form negative pressure, the negative pressure device collects toxic and corrosive gas generated in the formation process, performs centralized treatment, and does not discharge the toxic and corrosive gas into workshops and natural environment, thus improving the operation environment of operation staff, causing no pollution the environment, and being beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a novel chemical formation needle bed probe module. Background technique [0002] With the application of square aluminum lithium-ion batteries in various fields more and more popular, people have put forward higher requirements for the quality and utilization of square aluminum lithium-ion batteries. To meet this demand, the existing chemical formation needle bed mainly has the following problems: [0003] 1. The liquid injection port is open during the formation process, and the release of toxic gas generated during the formation process into the air will cause certain environmental pollution; [0004] 2. Due to the large amount of gas produced during the formation process of the battery case, the internal pressure of the battery case will increase, making it easier to bulge; [0005] 3. When the lithium-ion battery discharges gas, it cannot discharge the excess ele...
