What are the similarities and differences between alkaline batteries and carbon batteries?

Although our country is a big battery production country, but the battery leakage problem still exists, especially the dry battery. The dry batteries we use are mainly alkaline and carbon batteries, so carbon dry cell leakage and alkaline dry cell leakage is the same reason?

In general, the dry cell leakage and sealing process. For imported batteries, the use of excessive discharge will form a dry battery leakage, usually due to the output current is too large, continuous discharge time is too long, leading to the rise in battery temperature. Because the end voltage of the dry cell is 1v, theoretically, as long as the voltage below this continue to work may form a dry cell leakage, in the potential leakage of voltage design, some manufacturers promise 0.6 V, the best promise is 0.3V, but the latter is hard to come by. Improper application or defective design of the battery will result in the short connection of the positive and negative electrodes of the battery, causing a sudden high current in the battery, which directly causes the battery body to heat up, the resulting increase in temperature and pressure makes it possible for the gas to break through the valve, causing the dry cell to leak. The above is the two dry cell leakage common, there are some differences between the two.

First of all, the principle of leakage is not the same, carbon battery shell zinc skin as a negative electrode to participate in the reaction, the battery will soon run out of thin, especially below 1V still continue to use, there is a risk of leakage of dry battery, the alkaline dry cell leakage is not caused by chemical reactions, in addition to sealant aging reasons, there is the possibility of improper charging of the battery, so that the internal air pressure rise and the formation of battery leakage. Second, unlike the leaking liquid, the liquid in a carbon battery is zinc chloride and amine chloride, while the liquid in an alkaline battery is potassium hydroxide. The leakage of the dry battery will be seriously corrosive, not only to the environment has greater pollution, but also to the battery itself is a damage. Therefore, in order to ensure battery quality and solve the problem of battery leakage, has become an urgent task for battery manufacturers.
