Abstract

The utility model discloses a liquid storage tank for electrolyte, which comprises a tank body, a conduction pipe, a support column and a base, wherein the tank body is funnel-shaped and is made of 304 stainless steel material; a liquid level conduction pipe convenient for a user to observe is arranged on the side face of the tank body, and the conduction pipe is made of transparent materials; the support and the base maintain the stability of the tank body. The utility model provides a current electrolyte deposit fluid reservoir bottom surplus electrolyte too much problem when using can improve the utilization ratio of electrolyte. Meanwhile, the liquid storage tank can maintain a high liquid level only by a small amount of electrolyte, so that the abnormal phenomenon of less liquid injection caused by air bubbles sucked during liquid injection can be prevented, and the stability of the liquid injection amount is ensured.

Description

Liquid storage tank for electrolyte

Technical Field

The utility model relates to a lithium ion battery technical field especially relates to a liquid storage tank of electrolyte.

Background

Lithium ion batteries are one of the most widely used energy sources at present, and are continuously expanded and popularized in the fields of portable mobile power supplies, smart phones, notebook computers, tablet computers, cameras and other portable electronic products. With the popularization of the application, the cost performance of the product is required to be higher and higher by customers, so that manufacturers need to reduce the raw material cost in the production process as much as possible. The main raw materials for forming the battery are a positive electrode material, a negative electrode material, a diaphragm and an electrolyte, wherein the electrolyte is one of the main costs of the battery.

at present, in the production process of lithium ion batteries, most of electrolyte in a glove box is stored by adopting conical bottles or cylindrical tanks, the bottom areas of the tanks are large, the residual electrolyte is more and is 300-500 g when liquid injection is finished, and great waste exists.

In view of the above, it is desirable to provide a storage tank for an electrolyte solution to solve the deficiencies of the prior art.

Disclosure of Invention

The utility model discloses mainly be to prior art not enough, and provide a deposit fluid reservoir of electrolyte to solve the current electrolyte and deposit the too much problem of the remaining electrolyte in bottom when using of fluid reservoir, thereby reduce the waste of electrolyte, improve the utilization ratio of electrolyte.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The utility model provides a deposit liquid jar of electrolyte, includes a jar body, conduction pipe, pillar and base, jar body is the infundibulate, even has L type conduction pipe on the skew wall of jar body one side to with the export lower extreme UNICOM of the infundibulate type jar body, be provided with the pillar on the base in order to support jar body, maintain the stability of jar body.

the tank body is made of 304 stainless steel materials, the thickness of the tank body is 2 ~ 5 mm, the radius of the opening of the tank body is 0.8 ~ 1.0 dm, the height of the tank body is 1.5 ~ 2.0 dm, and the volume is 1.50 ~ 2.0L.

the conduction pipe adopts transparent material, for acid and alkali-resistant material, preferred PE, PP, its internal diameter is 6-8 mm, and the wall thickness is 1.0 ~ 2.0 mm to make things convenient for the user to observe the liquid level for the electrolyte.

the pillar be cylindrical, its diameter 8 ~ 10 mm has 2 ~ 4, plays the effect of connecting jar body and base.

the base is in an original annular shape, the outer diameter is 1.4 ~ 1.8 dm, the inner diameter is 1.2 ~ 1.4 dm, and the thickness is 5 ~ 8 mm.

The liquid storage tank is used for storing electrolyte in the hand box.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) The problem that the residual electrolyte at the bottom is excessive when the existing electrolyte storage tank is used is effectively solved, and the utilization rate of the electrolyte can be improved;

(2) The problem of current electrolyte deposit a small amount of electrolyte can maintain higher liquid level, inhale the bubble when preventing to annotate the liquid to guarantee to annotate the stability of liquid volume is solved.
