What is a disposable battery? Explain the working principle of disposable batteries in detail

Lithium-ion battery manufacturers explain that disposable batteries, disposable batteries are a kind of battery we often use, after a single use, there is no use. Disposable batteries can be divided into: carbon zinc batteries, alkaline batteries, paste zinc manganese batteries, cardboard zinc manganese batteries, alkaline zinc manganese batteries, button batteries (button zinc silver batteries, button lithium manganese batteries, button batteries Zinc-manganese batteries), zinc-air batteries, primary lithium-manganese batteries, mercury batteries. Traditional paste-type zinc-manganese dry batteries and cathode materials use natural manganese dioxide with low activity. The gasket is a separator of starch and flour paste, the electrolyte H4CL ammonium chloride, zinc chloride aqueous solution, and the cathode zinc tube. Its discharge performance is usually poor. Low capacity, easy to leak when the battery ends, but the price is cheap. According to the use of the separator, it can be divided into paste-type batteries and flat-type batteries. Flat-type batteries are divided into two types, C-type (ammonium type) and P-type (zinc-type) cardboard batteries according to different electrolytes. Cylindrical alkaline zinc-manganese batteries, also known as alkaline manganese batteries, are the best varieties in the zinc-manganese battery series. In the middle of the 20th century, the manganese-zinc battery was developed on the basis of the manganese-zinc battery, which is an improved version of the manganese-zinc battery. The battery uses potassium hydroxide (KOH) or sodium hydroxide (sodium hydroxide) in a liquid electrolyte aqueous solution, adopts the cathode structure of the zinc manganese battery, pastes the colloid, the liquid is connected to the battery by copper nails, the active material and the pressure ring The housing is made of conductive material, and the positive and negative electrodes are separated by a special diaphragm. The P-type (zinc) board uses zinc chloride battery electrolyte and cathode materials that are all made of highly active manganese powder, electrolytic manganese, manganese and other activities. The sealing performance is much higher than that of paste type and C-type batteries. They are mostly used for high-current continuous discharge. Occasion, such as used in cameras, flashes, tape recorders, razors, electric toys, etc. Based on the type C (ammonium) cardboard battery, the paste-type battery pulp layer paper replaces the sticky paper. Not only does the positive filling volume increase by 30%, the 30-70% high activity replaces natural manganese, the capacity is improved, and the scope of use is expanded. In the case of more small discharge currents, such as used in clocks, remote control, radios, flashlights, etc. The shell is made of 08f nickel-plated steel strip by cold stamping. At the same time, with the anolyte, the anode material of the electrolytic manganese dioxide battery forms a circle on the inner wall of the cylinder to ensure good contact. The cathode is made of zinc powder and made into a paste. In the battery, the negative current collector (usually, the cathode copper nail) is inserted, and the liquid at the bottom is connected to the negative electrode. Inside the battery, there is a separator (insulating) positive electrode, and the external nylon or polypropylene sealing ring is separated, and The battery is sealed, and the external battery is almost the same as the battery under normal circumstances.
