In addition, as the electric push rod drives the bending strip to move downward, the multi-inclined rod fixedly connected to the bottom of the bending sleeve will move downward and squeeze the top oblique circular sleeve inward, and the squeezed top oblique circular sleeve will be inserted toward the inner side of the motor housing.

At the same time, the above operation serves as a preliminary preparation for the subsequent filling of the conductive agent.

[0017] 3. The replacement head passes over the perforated disk and hits the film, causing the film to rupture and extend into the battery shell. Then, the conductive agent between the dumbbell rod and the replacement head will all enter the battery shell, thereby improving the conductivity of the positive electrode material, enhancing the electrode reaction activity and improving the stability of the electrode structure.

[0018] 4. By applying an appropriate low temperature on one side of the battery, the diffusion of lithium ions to this side is slowed down, while maintaining a relatively high temperature on the other side to promote the diffusion of lithium ions to that side. The distribution of lithium ions on the negative electrode surface is adjusted by the temperature difference to make it more uniform, avoiding the growth of lithium dendrites that interfere with power transmission.

By starting the electric push rod 262, the bending strip 263 connected to the telescopic end at the bottom thereof will move downward, and then the spring rod 264 connected to the bottom of the other end of the bending strip 263 will move downward with the inclined block 265, wherein the spring rod 264 plays a role in distance compensation and squeezes the inclined groove strip 266 outward, and the squeezed inclined groove strip 266 will move along the top of the battery shell 21 and toward the positive pole ear 22. At this time, the inorganic interface film 267 that was originally squeezed and limited by the inclined groove strip 266 will be released from the protective cover 268 and finally inserted into the interior of the motor shell 21, and its two sides will respectively fit and contact with the negative electrode material and the solid electrolyte 24, thereby modifying the surface of the negative electrode material and coating it with a thin layer of polymer or inorganic material, which can improve the compatibility between the electrode and the electrolyte, reduce the interface resistance, promote the migration of lithium ions at the interface, and prevent the growth of lithium dendrites, while improving the transmission efficiency of lithium ions at the interface.

[0038] like Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the conductive component 27 includes a multi-inclined rod 271, which is fixedly connected to the bottom of the bending strip 263, and the bottom of the multi-inclined rod 271 is extruded and adapted with a top oblique circular sleeve 272, which is inserted into the outer side of the battery shell 21, and the interior of the top oblique circular sleeve 272 is fixedly connected with an inner fixed cylinder 273, and the interior of the inner fixed cylinder 273 is slidably adapted with a dumbbell rod 274, and the inner end of the dumbbell rod 274 is fixedly connected with a replacement head 275, and the end of the dumbbell rod 274 away from the replacement head 275 is respectively fixedly connected with an extension rod 276 and a spring 277, and the ends of the extension rod 276 and the spring 277 away from the dumbbell rod 274 are fixedly connected with a triangular block 278, and the top of the triangular block 278 is extruded and adapted with a diamond block 279, wherein the triangular block 278 , diamond blocks 279 and components associated with the two, there are 5 of them, and each forms a group, wherein the triangular blocks 278 of the topmost group are fitted with the diamond blocks 279, and the next group below the topmost group, the triangular blocks 278 inside thereof will have a certain interval with the diamond blocks 279, so when the topmost group of diamond blocks 279 has completed the collision with the triangular blocks 278, the diamond blocks 279 of the group below it will be tightly attached to the top of the triangular blocks 278, thereby playing a role in filling the conductive agent in batches. When the power transmission is slow, the conductive agent filling can be carried out in five times. The inner side of the diamond block 279 is fixedly connected with a connecting rod 270, and the end of the connecting rod 270 away from the diamond block 279 is fixedly connected to the outer side of the multi-inclined rod 271. In addition, as the diamond block 279 continues to move downward, it no longer squeezes the triangular block 278. Then, under the elastic force of the spring 277, the replacement head 275 will be in the original position of the film 2703, thereby performing a position replacement process to prevent the positive electrode material from leaking out.

[0039] An internal groove 2701 is provided inside the battery shell 21, and a perforated disk 2702 is fixedly connected to the inner cavity of the battery shell 21, and a film 2703 is fixedly connected to the inner part of the perforated disk 2702.

At the same time, the folding rod 2708 fixedly connected to the outer side of the top oblique circular sleeve 272 will also move toward the direction of the battery housing 21 and insert into the inner side thereof, wherein the folding rod 2708 is fixedly connected to the second magnetic block 2709, so the second magnetic block 2709 will also be brought into the battery housing 21 by the folding rod 2708. In the inner groove 2701, the second magnetic block 2709 will be magnetically attracted to the number one magnetic block 2706 set inside the inner groove 2701. At this time, the sliding plate 2705 fixedly connected to the other end of the number one magnetic block 2706 will compress the return spring 2707 and move toward the direction of the inner rail 2704, so that the perforated disk 2702 and the film 2703 originally covered by the sliding plate 2705 will be exposed, wherein the sliding plate 2705 protects the film 2703 and prevents it from being damaged by external impact force. At the same time, the above operation serves as a preliminary preparation for the subsequent filling of the conductive agent.
