[0002] Lithium battery is a general term for chemical power sources with metallic lithium or lithium-containing substances as the negative electrode. Lithium-ion batteries have many superior characteristics, such as high energy, high safety, wide operating temperature range, stable operating voltage, and long storage life (relative to other batteries). When in use, the battery needs to be fixed by a clamp for charge and discharge testing. When in use, the existing clamps mostly clamp the battery with threaded rods, but this method can easily cause wear on the threaded rods as the use time increases, resulting in an impact on the clamping firmness of the battery. The clamp is applicable to a limited number of battery specifications and sizes, and this method only fixes the battery in the horizontal plane, which affects the battery cycle performance test. For this reason, we propose an adjustable battery test fixture. By adjusting the clamps in various directions, the purpose of multi-directional fixation of the battery is achieved.
