Small battery refers to a battery that can be used continuously after being charged. There are lead batteries, nickel-iron batteries and nickel-cadmium batteries. The positive electrode of the lead storage battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. During discharge (use), the positive and negative electrodes react with sulfuric acid to generate lead sulfate. When the concentration of the sulfuric acid solution drops to a certain level, it needs to be charged. When charging with an external power source, the electrodes and solution can be restored to their original state, and they can be used continuously after charging.
What are the general categories of small batteries? ? How much do you know about this problem? ? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some information on this issue. I hope it will be helpful to you. In the future, you can avoid detours when using and purchasing.
1. Ordinary storage batteries: The plates of ordinary storage batteries are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life, and frequent routine maintenance.
2. Dry-charged battery: The full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a higher power storage capacity. In a completely dry state, it can save the obtained power within two years. Just add electrolyte and wait for 20-30 minutes to use.
3. Maintenance-free battery: Due to the advantages of its own structure, the maintenance-free battery consumes very little electrolyte and basically does not need to be supplemented with distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of ordinary batteries. There are also two types of maintenance-free batteries on the market: the first one is to add electrolyte at the time of purchase, and there is no need to maintain (add supplementary fluid) in future use; the other is that the battery itself has been filled with electrolyte and sealed before leaving the factory. Dead, users can't add refill at all.
