Problems solved by technology

[0006] First, the heating of the electrolyte in the flask is carried out by a magnetic stirrer and stirred by a magnetic stirrer to ensure that the temperature in the flask is as uniform as possible. However, due to the rapid loss of heat above the flask, the liquid near the bottom of the flask The temperature is inconsistent with the temperature in the middle and above the flask, which will affect the accuracy of the life test
[0007] Second, due to the effect of electrolysis, harmful gases will be produced during the accelerated life test of the oxygen-titanium anode, which will affect the environment of the life test laboratory, have a greater impact on the health of laboratory personnel, and have a great impact on the electronics in the laboratory. Components corrode, reducing the lifespan of electronic equipment

Description

technical field [0001] The invention relates to the technical field of electrolysis, in particular to an oxygen-evolving titanium anode accelerated life testing device and an oxygen-evolving titanium anode accelerated life testing method. Background technique [0002] Oxygen-evolving titanium anode is an anode with a titanium-based metal surface coated with a catalytic coating (metal oxide coating, such as iridium dioxide, etc.), and its surface catalytic coating has an oxygen-evolving function. The quality of the oxygen-evolving titanium anode is directly related to its electrochemical performance stability in the electrolyte solution, and a good oxygen-evolving titanium anode should have a longer life. In order to accurately predict the life cycle of the oxygen-evolving titanium anode and ensure that the oxygen-evolving titanium anode can achieve the expected service life, it is necessary to conduct accelerated life sampling tests on the oxygen-evolving titanium anode duri...
