▎ 摘　　要

NOVELTY - The graphene composite electrode has an electrode structure (1) that is provided with a sliding cavity (2). The bottom surface of electrode structure is flush with the opening end surface of sliding cavity. A connecting groove (21) is formed on top surface of sliding cavity. The sliding cavity is provided with an extension portion at one end corresponding to length direction. An elongated sliding groove is formed on the bottom surface of extension portion. A sliding block is slidably connected inside the sliding groove. An L-shaped clamping plate (34) is symmetrically provided on the top surface of a chip board (3) along width direction. The clamping plate is provided with a first limiting plate and a second limiting plate that are connected vertically at the ends. The bottom end of the first limiting plate is vertically connected to outer edge of the top surface of chip board. Two symmetrical clamping plates are clamped in the sliding cavity to limit side portions and end surfaces. USE - Graphene composite electrode used in power system. ADVANTAGE - The electrode structure is conveniently and firmly connected with the chip board. The electrode structure is convenient to disassemble and replace, which greatly improves the stability and convenience of the graphene composite electrode in use. The slider is more easily and stably inserted into the card slot and is fitted closely and effectively to card slot. The instability of the electrode structure relative to the chip board due to the gap between the slider and side wall of the card slot is reduced. The stability and effectiveness of the electrode structure and chip board are improved after assembly. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the electrode structure and chip board before assembly.
