Description

Large-size battery structure convenient to assemble and disassemble Technical Field The utility model relates to the technical field of batteries, in particular to a large-size battery structure convenient to assemble and disassemble. Background Conventional button cells have the advantage of being efficient as a material screening tool, but the performance bias due to their simplified construction needs to be tightly calibrated. Although the miniature soft-package battery is closer to practical application, the research and development cost is high, the material consumption is large, and the miniature soft-package battery is particularly suitable for novel expensive materials. The soft package battery is complex in manufacturing process and packaging, and extra variables can be introduced in the research and development stage, so that the repeatability of the result is affected. In addition, the pouch cells are prone to swelling or leakage during testing, especially when testing high energy density materials, with potential safety hazards. The large-size battery capacity is between that of the traditional button battery and the miniature soft package, and the preparation process is very convenient compared with that of the soft package battery. However, when assembling a large-sized battery, a certain pretightening force needs to be applied to both ends of the electrode by using a clamp, and the conventional clamp structure is not convenient for assembling and disassembling the battery. Accordingly, there is a need to provide a large-sized battery structure that is convenient to assemble and disassemble to solve the above-described technical problems. Disclosure of utility model Aiming at the situation, in order to overcome the defects in the prior art, the utility model provides a large-size battery structure which is convenient to assemble and disassemble, and the large-size battery structure can clamp and fix a battery conveniently.
