The utility model provides a kind of electric-shock remelting's slab ingot crystallizer, including two groups of mutually symmetrical setting by corrugated working copper plate and being formed slab ingot crystallizer half module;Two groups of mutually symmetrical setting slab ingot crystallizer half module left and right ends are each equipped with connecting plate, bolt hole is equipped on connecting plate, and two groups of symmetrical setting slab ingot crystallizer half module are fixedly connected by bolt hole, and constitute slab ingot crystallizer.Combination slab ingot crystallizer by corrugated working copper plate is formed, and the working copper plate in width direction is greatly improved due to using folding process, and the deformation resistance of wide copper plate is greatly improved.Wide copper plate is decomposed into 6 strip copper plates with width W / 6 due to using corrugated process, and the working copper plate of electric-shock remelting slab ingot crystallizer is formed into corrugated structure with high stability, and the adjacent copper plate of each strip copper plate is connected in the form of fold line.

The button cell top cover assembly comprises the top cover assembly, the top cover assembly comprises an annular cover plate and a pole column, an annular insulating layer is arranged between the annular cover plate and the pole column, the annular cover plate comprises an inclined cover plate, the inclined cover plate is designed to be inclined downwards, and the annular insulating layer is arranged between the inclined cover plate and the pole column. An inclination angle alpha is formed between the inclined cover plate and the horizontal direction and ranges from 5 degrees to 15 degrees; according to the button cell top cover assembly and the lithium battery provided by the utility model, part or all of the annular cover plate is designed to be inclined downwards, so that expansive force is decomposed and expansive force in the vertical direction is inhibited, thus the reserved space is reduced, and the energy density is improved.

The application relates to the technical field of lithium batteries, and discloses a pole piece, a single battery and a pole piece manufacturing method. The pole piece comprises a plurality of foils, a plurality of first coating layers and a plurality of second coating layers. The plurality of foils are arranged at intervals, one side or both sides of the foils are provided with the first coating layers, and the second coating layers are arranged between adjacent foils to form a pole piece with a non-continuous foil structure. The second coating layers can provide a partial lithium deintercalation space between adjacent foils, and can effectively reduce the expansion degree of the pole piece in the first direction. Therefore, when the pole piece is used to manufacture an electric core, partial expansion reserved space can be released, the battery energy density can be improved, and in addition, the expansion force transmitted to the outside by the electric core can be effectively weakened, so that the safety is improved. The single battery with the pole piece also has the above advantages.

The utility model relates to wood door technical field discloses a kind of multifunctional anti-deformation wooden doors, including multiple spliced door panels, multiple spliced door panels are attached, and wood protective panel is respectively pasted in the two sides of multiple spliced door panels.The utility model provides that the clamping groove of spliced door panel side wall and the side wall of anti-coming-off clamping block are designed to cooperate, anti-coming-off clamping block slides into clamping groove along inclined plane during installation, transverse extrusion force generated by wedge structure is used, adjacent door panel is tightly locked, extrusion force is decomposed into normal pressure perpendicular to the wall of clamping groove, prevent door panel transverse displacement, while allowing small thermal expansion and contraction deformation, avoid stress concentration to lead to cracking, polyurethane foam strip in anti-deformation clamping frame inner wall has elasticity, can buffer the expansion force generated by humidity change of door panel, wear-resistant rubber pad on outside is closely attached to door panel surface, inhibit door panel warping by friction force, while reducing the direct friction loss between clamping frame and door panel.
