Many people know that dry batteries are divided into two types: acid batteries and alkaline batteries, but they don't know what the difference is between the two, and which one is better for acid batteries and alkaline batteries? Choose alkaline batteries whenever possible!
Regarding the acid battery: From a professional point of view, the full name of the acid battery should be the acid zinc manganese dry battery. The reaction inside the acid battery is acidic. During the discharge process of the battery, the pH value changes from 5 to 7. Its basic The structure was first determined by the French scientist Leclanchette, so it is also known as the Leclanchette battery. In order to be uniform, to reduce the corrosion of zinc and improve the storage performance of the battery, the positive electrode material is a mixed paste composed of manganese dioxide powder, ammonium chloride and carbon black. A carbon rod is inserted in the middle of the positive electrode material as a conductor for drawing out the current. There is a layer of reinforced separator paper between the positive electrode and the negative electrode, which is saturated with an electrolyte solution containing ammonium chloride and zinc chloride, and the upper part of the metal zinc is sealed.
As for alkaline batteries: from a professional point of view, the full name of alkaline batteries should actually be alkaline zinc-manganese batteries. The alkaline batteries were successfully developed in 1882 and developed in 1912, but were not put into production until 1949. . It has been found that when KOH electrolyte solution is used instead of NH4Cl as the electrolyte, there are great changes in both electrolyte and structure, and the specific energy and discharge current of the battery can be significantly improved. Alkaline batteries are more durable than acid batteries.
In addition, although acid batteries are rich in raw materials and low in price, they have many disadvantages: the voltage continues to drop during use, and a stable voltage cannot be supplied, and the discharge power is low, the specific energy is small, and the low temperature performance is poor, and it cannot work at -20 ℃. Only alkaline zinc-manganese dry batteries can be used in alpine regions.
On the other hand, the performance of alkaline batteries is greatly improved compared with that of acid batteries. For example, 1. It has a wider working temperature range. The working range of alkaline batteries is between -20°C and 60°C, which can be applied to more 2. The capacity of high current continuous discharge is about 5 times that of the acid zinc-manganese battery, that is to say, one alkaline battery is equivalent to five acid batteries; 3. Its low temperature discharge performance is also very good Well, it can still work normally under low temperature conditions, supply enough power for the equipment, and then ensure the normal use of the equipment!
The above is the introduction about the comparison of alkaline batteries and acid batteries. Chung Pak is an exporter of alkaline batteries from China.
