Title:
IN SITU THREE-ELECTRODE TESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/095704
Kind Code:
A1
Abstract:
Disclosed is an in situ three-electrode testing system, comprising an inert gas environment sealing apparatus, a three-electrode apparatus, a battery testing device, a voltage testing device and a data collection device, wherein the three-electrode apparatus, the battery testing device, the voltage testing device and the data collection device are placed at the inner end portion of the inert gas environment sealing apparatus; the three-electrode apparatus is respectively connected to the voltage testing device and the battery testing device; and the battery testing device and the voltage testing device are connected to the data collection device. According to the present invention, the key problems of three-electrode testing are solved, and the problem that electrolyte and lithium reference electrode denaturation occurs due to the fact that a three-electrode apparatus is affected by external water and oxygen is avoided. In the present invention, an integrated lithium reference electrode is used, and data test inaccuracies caused by the problems that the contact between the lithium reference electrode and a wire is poor, a side reaction is caused and the like are avoided.
