This invention discloses a compound traditional Chinese medicine powder inhaler for respiratory tract infections and its preparation method, relating to the field of pharmaceutical formulation technology. The compound traditional Chinese medicine powder inhaler for respiratory tract infections is composed of polysaccharide composite gel microspheres, forsythia, scutellaria, honeysuckle, and isatis root. The polysaccharide composite gel microspheres are composed of seaweed sulfated polysaccharide, lentinan, calcium chloride, and curcumin. Seaweed sulfated polysaccharide, lentinan, curcumin, and calcium chloride cross-link to form a three-dimensional network spherical structure, improving the particle morphology and flowability of the micropowder. Furthermore, due to its good hygroscopic and moisturizing properties, it competitively reduces the moisture absorption of the micropowder, preventing aggregation and further improving flowability. In addition, the gel microspheres have excellent adhesion, adhering to the infection site after entering the respiratory tract, reducing expulsion losses due to respiration, maintaining an effective drug concentration at the infection site, and improving therapeutic efficacy.

This invention provides a bipolar electrode and a bipolar all-solid-state battery. The bipolar electrode comprises a positive electrode film, a current collector, a bulk material layer, and a carbon material layer. Through the design of the carbonaceous framework and nucleating agent in the bulk material layer, efficient and dense lithium metal deposition is achieved under high voltage conditions. The carbon material layer significantly improves the interfacial contact between the bulk material layer and the all-solid-state electrolyte, reduces interfacial resistance, and improves the deposition and extraction efficiency of lithium metal in the bulk material layer. Furthermore, the carbon material layer provides storage space for lithium metal deposited from the positive electrode, mitigating volume changes during lithium metal deposition in the bulk material layer and improving the stability of the bipolar electrode. The bipolar all-solid-state battery fabricated using the bipolar electrode exhibits high rate capability and long lifespan.
