Today, people's environmental awareness is continuously strengthened, commonly used alkaline batteries have achieved low and mercury and even mercury, in which the choice of alloy gold powder is the main improvement measures for alkaline battery low and mercuryization.Extremely low mercury, first-rate zinc powder alloy to meet the following conditions: (1) It is difficult to corrode in the shouting electrolyte; (2) has no adverse effect on zinc powder; (3) does not include or less harmful addition Element; (4) Zinc powder is high; (5) There is not much increase in material cost. The basic zinc manganese battery zinc powder is queriated, mainly to increase the hydrogen excess of zinc powder in the shouting electrohydrate to inhibit hydrogen in the alkali solution. The amalgam formed by zinc powder is uniformly flat to cover the surface of the zinc powder, thereby changing the surface condition of the zinc particles, activating the zinc electrode, thereby increasing the electrical energy of the battery, reducing the drain of the battery. During the battery discharge, mercury is diffused inside the zinc particles on the surface of the zinc particles, so that the discharge is smooth. Therefore, under the conditions of low mercury, the zinc powder corrosion must be added with an appropriate amount of a microcontroller that can increase the hydrogen excessive potential, prevent mercury from being diffused to zinc particles inside the zinc particles in the zinc particles, and does not affect the discharge In the range of the reaction, the zinc powder ratio surface area is appropriately reduced.
Selecting micro-adding elements typically uses indium to add an element because it can not only improve the hydrogen overvoltage surface of the zinc alloy particles, but also easy to make zinc surfaces and mercury to form alloys, and the addition effect is more obvious. Therefore, indium ingo rosks are low-merciedized zinc-free zinc powder, which is currently necessary to add an element. Other add elements are: lead, aluminum, bismuth, cadmium, etc., cadmium elements themselves high, so there is good corrosion resistance, but they are toxic, and use as little as possible in certain low and mercury or mercury-free batteries Or not.
Battery manufacturers have also taken an organic boundary active agent to be added, and the treatment of silver nails are treated in the production of low and mercuryized alkaline batteries.
