This invention relates to the field of battery technology, and more particularly to a positive electrode lithium replenisher, its preparation method, a positive electrode sheet, and a lithium battery. The aforementioned positive electrode lithium replenisher includes a core and a shell, with the shell covering the surface of the core to isolate the core from the side reaction environment.

The microcapsule self-repairing technology is introduced into the field of magnesium-based hydrogen storage materials for the first time, the capacity attenuation problem caused by the recycling pulverization of the magnesium-based material is effectively solved, the service life of the material is significantly prolonged, and the capacity retention rate is not less than 90% after 100 cycles.

This utility model discloses an insulating layer coating device for insulating paper, belonging to the field of insulating paper processing technology. The device includes a main body, with transmission mechanisms fixedly connected to both ends of a rotating shaft, and reciprocating mechanisms fixedly connected to the outward-facing ends of two scrapers. A reset mechanism is connected between the first support and the scraper, and a scraping mechanism is slidably connected to the inward-facing ends of both first supports. This utility model significantly optimizes the insulating paper coating process through an innovative design of a linkage-type mechanical transmission and an elastic reset mechanism. The transmission mechanism drives the scraper in automated reciprocating motion, eliminating the need for an additional power source and significantly improving coating efficiency. The scraper removes excess liquid from both ends of the roller shaft in real time, preventing contamination of the insulating paper edges and ensuring uniform coating quality. The inclined scraper guides the coating liquid back to a collection box, enabling resource reuse and reducing production costs.
