The invention relates to the field of electrochemical generators, in particular alkaline generators, and more particularly to that of accumulators. It especially relates to secondary generators with a zinc anode. It relates in particular to a method for preparing an electrochemical generator, comprising the steps of: • assembling a hydrophobic membrane with a cathode and a zinc anode, and then • adding an electrolyte which is an alkaline aqueous solution comprising at least one wetting agent and at least one antifoaming agent. The invention also relates to an electrochemical generator obtained by the method according to the invention.

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.
