This invention relates to a PbS-modified AgO cathode material, its preparation method, and a zinc-silver battery, belonging to the field of zinc-silver battery technology. The PbS content is 1% to 5% of the AgO cathode material's mass, and it is prepared by wet mixing and ball milling. Adding PbS to the AgO cathode material and ball milling it to generate PbSO4 not only inhibits the decomposition of AgO during ball milling but also inhibits the decomposition of AgO during aging. This cathode material can extend the battery's lifespan during long-term storage of zinc-silver batteries.

This invention discloses an automated system and method for preparing zinc-silver battery positive electrode plates, belonging to the technical field of battery manufacturing equipment. Addressing the challenges in zinc-silver battery positive electrode plate preparation, such as powder stratification and agglomeration, plate fragility, long sintering cooling time, and low detection accuracy, this invention proposes the following innovations: Powder weighing utilizes a combined rotary screw and belt feeding system, achieving non-extrusion and flipping conveying and low-drop-height flat laying, avoiding cold welding of silver powder and silver-carbon stratification; preheating the mold before pressing improves density uniformity; sintering employs a double-layer circulating tunnel furnace with an air-cooled outlet unit, shortening cooling time; the robotic arm end uses a flexible suction cup and S-curve acceleration / deceleration control to achieve damage-free transfer of fragile plates; and integrated detection includes weighing, five-point coaxial thickness measurement, and deep learning appearance recognition, significantly improving detection accuracy. This invention achieves full-process automation, increasing production efficiency, reducing labor costs, lowering scrap rates, and significantly improving product consistency and reliability.

The invention discloses a method for improving floating charge performance of a zinc-silver reserve battery, belongs to the field of design of the zinc-silver reserve battery, and aims to discharge the capacity of the zinc-silver reserve battery to 70-80% of the capacity of the zinc-silver reserve battery after formation charging in the production process of the zinc-silver reserve battery, and the open-circuit voltage of a single battery is 1.60-1.70 V. The zinc-silver reserve battery is used for connecting a power generation system in parallel. When the positive electrode plate and the negative electrode plate are pre-discharged in the production process and are connected with a power generation system in parallel, the battery can be immediately discharged to work and can also be immediately charged, and the risk of overcharging or overdischarging does not exist. The positive and negative plates can change along with the voltage of the power generation system through pre-electrification, thereby preventing overlarge difference between the voltage of the battery pack and the voltage of the power generation system from causing overlarge charging or discharging current of the battery pack.
