Description

Clamping device for solid-state battery test Technical Field The utility model relates to the technical field of battery testing fixtures, in particular to a clamping device for testing a solid-state battery. Background A solid-state battery is a battery technology that uses a solid-state electrolyte instead of a liquid electrolyte in a conventional lithium ion battery. In order to ensure that the solid-state battery product meets the product requirements and the consistency of the product quality and performance, the solid-state battery needs to be tested. Current chinese patent (CN 222189342U) discloses a clamping device for solid-state battery test, which comprises a base plate, wherein the base plate is provided with a clamping mechanism, the rear end of the upper surface of the base plate is provided with an electric push rod, the output end of the electric push rod is provided with a clamping platform, the upper surface of the clamping platform is provided with a solid-state battery, four corners of the lower surface of the clamping platform are provided with rollers, and the rollers are in contact with the upper surface of the base plate. When the clamping device is used, the clamping platform is pushed out through the electric push rod, the electric push rod is retracted after the solid-state battery is placed on the surface of the clamping platform, then the solid-state battery can be clamped through the clamping mechanism, the testing work is convenient to develop, in the scheme, the solid-state battery is not collided with other parts in the process of placing the solid-state battery, and the damage of the solid-state battery due to collision is avoided. When the solid-state battery is subjected to unfolding test, the testing links of the positive electrode and the negative electrode are important. In order to obtain comprehensive and accurate test data, the solid-state battery to be fixed needs to be subjected to positive and negative electrode turning operation. However, with the clamping device used in the current solid-state battery test, there is a general disadvantage in that it is difficult to automatically turn over the anode and the cathode. In the actual test process, the battery often has to be turned over manually, so that the test efficiency is greatly reduced. Disclosure of utility model The utility model aims to provide a clamping device for solid-state battery test, which is used for solving the problems in the background technology.
