Description

Technical Field

[0001] This utility model belongs to the technical field of chemical material testing equipment, specifically relating to a halide air stability testing device. Background Technology

[0002] Halogen electrolyte materials have attracted increasing attention in the field of solid-state batteries, but their insufficient chemical stability in humid air severely restricts their practical application. Current testing methods for the air stability of halides mostly rely on traditional manual operations, such as exposing samples to a constant temperature and humidity chamber and assessing the degree of decomposition through periodic sampling and weighing or spectral analysis. These methods have significant drawbacks: firstly, frequent manual intervention leads to low testing efficiency and makes it difficult to capture the impact of instantaneous humidity fluctuations on the material; secondly, volatile products generated during halide decomposition are directly released into the environment during testing, causing toxic gas pollution and making it impossible to deduce the material decomposition kinetics through quantitative collection; thirdly, traditional vacuum drying ovens typically use vacuum pumps to directly extract volatile gases when handling solvent-containing halide samples, resulting in solvent waste and secondary pollution.

The connection part of the first pipe 411 and the exhaust gas discharge pipe 31 is located on the side of the exhaust gas valve 32 away from the drying box 3.

[0037] The working principle of the halide air stability testing device provided in this embodiment is as follows:

[0038] First, the glove box 1 is filled with inert gas. Then, the sample to be tested is placed in the drying oven 3 for drying. Organic waste gas is generated during the drying process. The waste gas valve 32 is opened, and the organic waste gas can be discharged through the waste gas discharge pipe 31. If the organic waste gas contains large molecules such as benzene, ketones, and esters, the first valve 412 is opened. The organic waste gas flows into the first adsorption tank 41 along the waste gas discharge pipe 31 and the first pipe 411. All the organic waste gas is adsorbed in the first adsorption tank 41. After adsorption is completed, the first valve 412 is closed, and the second valve 414 and the third valve 416 are opened. Steam is introduced into the first adsorption tank 41 through the third pipe 415. The steam carries away the organic components adsorbed in the first adsorption tank 41 and flows into the heat exchanger 43 through the second pipe 413. In the heat exchanger 43, the steam containing organic components is condensed into liquid. The seventh valve 431 is opened, and the condensed liquid flows into the solvent recovery tank 44 along the seventh pipe for temporary storage, thus completing the recovery of organic waste gas.

[0039] If the organic waste gas contains small molecules such as alcohols and aldehydes, then close the first valve 412, the second valve 414, and the third valve 416, and open the fourth valve 422. The organic waste gas flows into the second adsorption tank 42 along the waste gas discharge pipe 31 and the fourth pipe 421. The organic waste gas is completely adsorbed in the second adsorption tank 42. After adsorption is complete, close the fourth valve 422, and open the fifth valve 424 and the sixth valve 426. Steam is introduced into the second adsorption tank 42 through the sixth pipe 425. The steam carries away the organic components adsorbed in the second adsorption tank 42 and flows into the heat exchanger 43 through the fifth pipe 423. In the heat exchanger 43, the steam containing organic components is condensed into liquid. Open the seventh valve 431, and the condensed liquid flows into the solvent recovery tank 44 along the seventh pipe for temporary storage, thus completing the recovery of organic waste gas.

[0040] Meanwhile, the dried sample is taken out from the drying oven 3 through the operation window of the glove box 1, then weighed by the balance 13, and the sample is transferred by the lifting platform 14. The sample to be tested is added into the reaction vessel 15, and the weight change of the sample is recorded every hour through the reaction vessel. The dew point environment change curve in the built-in sensor detection system is used to finally measure the conductivity of the sample in the reaction vessel after being exposed to a certain dew point for 6 hours.

[0041] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
