This invention provides a rigid polybutylene succinate (PBS) biodegradable sheet and its preparation method. The biodegradable sheet comprises, by weight: 40-55 parts PBS, 40-50 parts core-shell composite material, 3-5 parts polylactic acid (PLA), 1-2 parts compatibilizer, 0.3-0.5 parts lubricant, and 0.5-1.0 parts nucleating agent. This invention utilizes anhydride to mechanically modify starch under dry conditions, causing esterification and anhydride adhesion to the surface of starch particles. Low molecular weight PBS is then extended and anchored onto the surface of the starch particles via hot-melt extrusion to form a core-shell composite material. This core-shell composite material significantly increases rigidity, prevents starch particles from being exposed, and exhibits excellent compatibility with the PBS matrix. The prepared sheet does not swell or precipitate after boiling. This production technology uses simple raw materials, the hot-melt extrusion equipment is suitable for large-scale production, the biodegradable sheet has a high starch content, and the overall cost is low.

This invention relates to a granulated body prepared from ceramic powder, its preparation method, and its application. The preparation method includes using ceramic powder as raw material and using smooth micro-granules with a particle size of 400 mesh or larger and 100 mesh or smaller as a barrier. The composition of the barrier is the same as that of the ceramic powder used as raw material. The ceramic powder and the barrier are mixed and granulated using a rolling granulation method. After granulation, the granules are sieved to obtain granules with a particle size of 40-100 mesh. This method does not require the addition of any binder. By adding the barrier, the yield of 40-100 mesh granules after a single granulation of ceramic powder is significantly improved, and the yield increases with the increase of the amount of barrier added, which can significantly improve the effective utilization rate of ceramic powder. The green body obtained by pressing the 40-100 mesh granules obtained by this method has a uniform mass distribution and can be used to prepare optical glass.

This invention relates to the field of sodium-ion battery technology, specifically disclosing a sodium-ion battery cathode material, its preparation method, a battery cell, and a battery. The cathode material involves the sequential stacking of single-crystal particles, near-single-crystal particles, and aggregated particles along a vertical direction from a foil substrate. The single-crystal particles are single, blocky crystals; the near-single-crystal particles are secondary particles formed by the stacking and connection of multiple single-crystal particles, which are mixed with and fill the gaps between the single-crystal particles; the aggregated particles are secondary particles formed by the stacking of multiple micro / nano particles, used to provide a rapid migration channel for ions at the cathode, shortening the ion migration distance and enabling fast charging of the sodium-ion battery. This invention involves the sequential stacking of three layers of three types of active particles—single-crystal particles, near-single-crystal particles, and aggregated particles—starting from the vertical direction of the foil substrate. This multi-gradient cathode material design greatly improves the space utilization and energy carrying capacity of the active material on the electrode, while also providing fast charging capability.
