Model naming and identification

Structure and characteristics
1. Cylindrical zinc-manganese battery Cylindrical zinc-manganese battery can be divided into paste battery and cardboard battery according to the difference of the separator. The paste type battery is a common type of zinc-manganese battery, and the cardboard battery is divided into a C-type (or ammonium type) cardboard battery (also called a high-capacity battery) and a P type (or called) due to differences in the composition of the composition. Zinc type) cardboard battery (also known as high power battery).
Paste battery is a traditional zinc-manganese dry battery. Its positive electrode material uses low-activity natural manganese dioxide. The separator is a paste separation layer of starch and flour. The electrolyte is mainly ammonium chloride and zinc chloride based on H4CL. The aqueous solution and the negative electrode are zinc cylinders, and their discharge performance is generally poor, the capacity is low, and the battery is easy to leak at the end of use, but the price is cheap, and is suitable for occasions of small current and intermittent discharge, such as for radios, flashlights, and the like.
The C-type cardboard battery replaces the paste paper with a layer of paper on the basis of the paste battery, which not only increases the positive electrode filling amount by about 30%, but also replaces the natural manganese with 30-70% of high-activity manganese, so the capacity is improved. The scope of use has been expanded, and it is mostly used in small current discharge applications, such as in watches, remote controls, radios, flashlights, etc.
The P-type paperboard battery uses zinc chloride-based electrolyte, and the positive electrode materials all use high-activity manganese powder, such as electrolytic manganese, activated manganese, etc., and its leakage prevention performance is much higher than paste and C-type batteries, and is mostly used for high current. For continuous discharge applications, such as for cameras, flash sets, tape recorders, razors, electric toys, etc.
2. Cylindrical alkaline zinc-manganese dry battery Cylindrical alkaline zinc-manganese battery, also known as alkaline manganese battery, commonly known as alkaline battery, is the best performance of zinc-manganese battery series. The outer casing is generally made of 08F nickel-plated steel strip by cold rolling stamping, and also serves as a positive current collector. The electrolytic manganese dioxide cathode material is pressed into a ring to adhere to the inner wall of the column to ensure good contact, and the negative electrode is powdered. The zinc particles are made into a paste, which is placed in the middle of the battery, and a negative current collector is inserted therebetween (the negative electrode is generally a copper nail), and the current collector is connected to the bottom of the negative electrode. Inside the battery, the positive electrode is separated by a separator (separation layer), and the external portion is used. The nylon or polypropylene sealing ring is separated, and the battery is sealed at the same time. The outside of the battery is almost the same as the general battery.
Although the nominal voltage of the cylindrical alkaline zinc-manganese battery is the same as that of the ordinary battery, both of which are 1.5 volts, since the alkaline battery is structurally used in the opposite electrode structure of the ordinary battery, the relative area between the positive and negative electrodes is increased. Moreover, the ammonium chloride solution and the zinc chloride solution are replaced by a highly conductive potassium hydroxide solution, and the negative electrode zinc is also changed from a sheet to a granular shape, thereby increasing the reaction area of ​​the negative electrode, and using a high-performance electrolytic manganese powder, The electrical performance is greatly improved. Generally, the alkaline manganese battery of the same type is 3-7 times of the capacity and discharge time of the ordinary battery, and the difference between the low temperature performance is greater. The alkaline manganese battery is more suitable for continuous discharge and demand of large current. High working voltage, especially suitable for cameras, flash sets, razors, conductive toys, CD players, high-power remote controls, etc.
