Problems solved by technology

[0003] There are certain shortcomings in the above two methods respectively: although the method of using copper foil (or aluminum foil) as a carrier is simple, the copper and aluminum foil cannot be reused. It is easy to oxidize under baking, which affects the test results, resulting in certain test errors. In addition, the instrument test defect of the infrared moisture tester is that its price is relatively expensive. If the above problems can be solved by making certain improvements to the test carrier, a win-win situation will be achieved. will solve the above problem

Abstract

The invention discloses a battery slurry solid content test device and test method. The device is specifically a concave type tray. The concave type tray comprises a tray bottom and an external rim. The concave type tray is made of a composite material. The specific raw materials for preparing the composite material comprise the following ingredients: C: 0.03-0.06%, Si: 0.6 -0.8%, Mn: 2-2.1%, Cr:19.0-22.0%, Ni: 9-11. 5%, N: 1.0-1.2%, and the balance being Fe. Compared with the prior art, the device has the following advantages: 1) the design of the concave type tray structure effectively ensures storage stability of the slurry to be tested in the taking and putting, testing and transporting process, and reduces splashing; 2) the test device prepared through the composite material is low in oxidation activity, is high in high-temperature tolerance and can maintain constant weight before or after baking, thereby reducing errors caused by the device itself of the test method; and 3) thetest method is simple, and the device is low in cost.

Description

technical field [0001] The invention relates to the testing field of lithium ion battery slurry, in particular to a battery slurry solid content testing carrier and a testing method. Background technique [0002] At present, there are two main methods for testing the solid content of lithium-ion battery slurry. One is to use copper foil (or aluminum foil) as a carrier. Calculate the solid content by weight before and after baking; the other is to use an infrared moisture tester, smear the slurry on the copper foil (or aluminum foil), put it in the tray, click to heat, and the instrument will automatically display the solid content data after drying. [0003] There are certain shortcomings in the above two methods respectively: although the method of using copper foil (or aluminum foil) as a carrier is simple, the copper and aluminum foil cannot be reused. It is easy to oxidize under baking, which affects the test results, resulting in certain test errors; in addition, the i...
