This structure can make the silicon material effectively adsorb on the surface of the graphite, avoiding the agglomeration of the silicon material itself and the interaction with the graphite. It has the characteristics of adjustable charge-discharge specific capacity and high electrochemical cycle stability.

The invention discloses anti-theft equipment for education documents based on big data. The anti-theft equipment comprises an equipment body, wherein a fixed seat is embedded in the bottom end of the equipment body, and a sealing cabinet door is movably hinged to the surface of the equipment body; a locking block is fixedly arranged on the surface of the sealing cabinet door, and an adaptive round hole is formed in the surface of the locking block; a stable top plate is fixedly arranged at the top end of the equipment body; a linkage assembly is rotationally connected to the surface of the inner wall of the sealing cabinet door; and a driving structure is attached to one end of the linkage assembly. According to the anti-theft equipment, by arranging a limiting assembly and utilizing the limiting and clamping functions of an air cushion of the limiting assembly, a fixed long plate is not prone to sliding out of the interior of the limiting assembly when the fixed long plate is stably attached to the interior of the limiting assembly, then the use effect of the fixed long plate is guaranteed, and the use value of the equipment is further increased; and the accident problem that the fixed long plate is opened by mistake is avoided, and the adaptation range of the equipment is further widened.
