AI Technical Summary

Problems solved by technology

The lack of methods and devices suitable for the study of high-gravity electrochemical reactions is the main problem restricting the development of high-gravity electrochemical reactions. Therefore, creating a stable high-gravity environment and realizing the smooth progress of electrochemical reactions in the high-gravity field promotes the development of high-gravity electrochemical reactions. The development in the electrochemical industry is an urgent problem to be solved, because some mature experimental techniques and control methods under conventional gravity conditions are no longer fully applicable in the process of high-gravity electrochemical research, and existing commercial equipment Or the lack of certain technical functions, or the difficulty of integration between different systems, etc., cannot meet the needs of the development of high-gravity electrochemical science

Some foreign institutions engaged in high-gravity electrochemical research set up experimental devices only for the purpose of satisfying preliminary electrochemical experiments, and did not establish mature high-gravity electrochemical reaction methods and standard high-gravity electrochemical reaction device assembly methods. , the transmission accuracy of the electrochemical signal and temperature signal in the reaction device can not meet the requirements, and the monitoring of the electrode surface reaction state and the gas collection and atmosphere control in the electrochemical reaction system are powerless; The research on the device and method of gravitational electrochemical reaction is still in the blank stage
