Name and Constructure of Zinc-manganese battery
Structure and characteristics
1. Cylindrical zinc-manganese batteries
Type cylindrical zinc-manganese batteries in the isolation of the different materials can be divided into cardboard paste-type cells and batteries. Paste manganese batteries or batteries zinc-normal type, battery board to differences in the composition of the formulations of different electrical properties, is divided into C-(or ammonium type), the piles of cardboard (also known as high-capacity battery), and P-type (or zinc type) fiber cells (also known as high-power batteries).
Pasta type battery which is the traditional zinc manganese batteries, the cathode material with a low activity of natural manganese dioxide, insulation material is starch and flour insulating paste layer, the electrolyte is H4CL mainly ammonium chloride, zinc chloride aqueous solution, the negative electrode is zinc cylinder, the poor overall performance of your bottom discharge capacity of the easy life of the battery to drain, but the price is cheaper, more suitable for small intermittent streams and download times, as for radio, flashlight, etc..
C-board battery is the battery on the paste on the base layer of paper pulp instead of using paper tape, not just positive increased by 30% of filler content, but with 30-70% of the high VGP-BPS10,,VGP-BPS10A,VGP-BPS10A/B,VGP-BPS10Bactivity of manganese in place of natural manganese, so the capacity will increase the use of scope could be expanded and used to sometimes low discharge current, such as clocks, remote controls, radios, flashlights and other occasions.
P-board battery using zinc chloride-based electrolyte, the cathode material used in all activities of high manganese dust, such as manganese, manganese and assets leak proof performance, much larger than the type of pulp and C-type batteries, often used for high power continuous discharge, such as cameras, flash setting, tape recorders, shavers, electric toys.
2. Cylindrical alkaline battery
Cylindrical alkaline zinc-manganese batteries, also known as alkali-manganese batteries, commonly known as the alkaline zinc manganese series battery, performance is the best variety. The shell has generally 08F nickel-plated steel is made by cold pressing at the same time serve as cathode current collector, electrolytic manganese dioxide as cathode material pressed into the ring closure to the cylinder wall to ensure good contact, the negative use of powder made of zinc tablets, and pastes, in the midst of the battery, the negative current collector inserted (usually negative Brass Nails), set the bottom of the fluid and connected to negative the battery inside the cathode to the gap between the layer (separation) separated from its external use nylon or polypropylene ring off, while achieving a sealed battery, the battery outside the battery is almost the same with the general.
Although the cylindrical alkaline zinc-manganese battery rated voltage of the battery the same as the ordinary, are 1.5 volts, but because the structure of alkaline batteries used in the normal versus the electrode structure, increases the relative size between the positive and negative electrodes, and high electrical conductivity of potassium hydroxide solution replaces the ammonium chloride, zinc chloride solution, the zinc anode can also be changed by the blade in a grainy, increase the reaction surface of the negative electrode, combined with the use of a high performance powder manganese, electric mode can profile greatly improve performance and, in general, the same type of alkaline manganese batteries are standard battery capacity and discharge time of 3.7 times greater gap between the two low-temperature properties, alkali-manganese battery is best suited to carry large current and demanding continuous operating voltage of the electricity sometimes, especially for the camera, the flash set, razor, toys driving machine CD control high power distance and so on.
