Solid electrolyte testing device

The utility model provides a solid electrolyte testing device. The solid electrolyte testing device comprises a detachable and assembled first part clamp part, a second part test system used for clamping and testing a solid electrolyte, and a tabletting die device used for manufacturing a solid electrolyte sample piece suitable for the first part clamp part, the negative electrode shell, the elastic sheet, the current collector I, the solid electrolyte sample sheet, the current collector II and the positive electrode shell are sequentially assembled on the clamp part from top to bottom; and athrough hole is formed in the negative electrode shell. The solid electrolyte testing device can ensure that the temperature and the humidity of a sample in the clamp part are consistent with the environment outside the clamp part in the testing process, thereby ensuring the accuracy of the ionic conductivity test of the solid electrolyte under different humidity and temperature, and enabling theinterior of the clamp part
