An electrochemical test device for solid electrolyte

Abstract

The invention relates to an electrochemical testing device for solid electrolyte, which includes a support member, a pusher member, a mobile pusher device and an electrode fixing member for fixing a working electrode. The support member includes a support member for vertically supporting the solid electrolyte. The supporting part and the limiting part for horizontally limiting the solid electrolyte, the limiting part is provided at one end of the supporting part. The pushing member is supported on the supporting part and can move back and forth along the length direction of the supporting part. The mobile pushing device is located at an end of the support member away from the limiting portion and is fixed with the pushing piece to drive the pushing piece to move back and forth. The electrochemical testing device of the present invention can ensure stable point contact between the working electrode and the solid electrolyte, greatly reducing the test error and making the test results more consistent.
