Do you know what is the voltage range of the dry battery?

Dry batteries are chemical batteries that use paste electrolyte to generate direct current (wet batteries are chemical batteries that use liquid electrolyte). They are roughly divided into primary batteries and secondary batteries. They are commonly used in daily life. , And a lightweight battery. They can be used in many electrical appliances. Let's take a look at the specific voltage range of the dry battery, right? Ordinary batteries are 1.5v, nickel-cadmium or nickel-metal hydride rechargeable batteries are 1.2v, there are also cylindrical lithium-ion batteries 3.7v, storage batteries 2v, etc., Europe also has a zinc rechargeable battery 1.9v. Dry battery belongs to the primary battery in chemical power supply and is a kind of disposable battery. Because the electrolyte of this kind of chemical power supply device is a kind of non-flowable paste, it is called a dry battery, which is related to a battery with a flowable electrolyte. Dry batteries are not only suitable for flashlights, semiconductor radios, tape recorders, cameras, electronic clocks, toys, etc., but also for various fields in the national economy such as national defense, scientific research, telecommunications, navigation, aviation, and medicine. Ordinary dry batteries are mostly manganese-zinc batteries, with a positive carbon rod in the middle, a mixture of graphite and manganese dioxide, and a layer of fiber mesh. The mesh is coated with a thick electrolyte paste, which is composed of ammonium chloride solution and starch. There is also a small amount of preservative. The outermost layer is a cylinder made of metal zinc skin, which is the negative electrode. The discharge of the battery is the electrolytic reaction of ammonium chloride and zinc, and the released charge is conducted by graphite to the positive carbon rod. The electrolytic reaction of zinc is It will release hydrogen. This gas will increase the internal resistance of the battery. The manganese dioxide mixed with graphite is used to absorb hydrogen. But if the battery continues to work or is used for too long, the manganese dioxide will be too late or too late. It is nearly saturated and unable to absorb any more. At this time, the battery will lose its use due to too much internal resistance and too small output current. But if the battery is heated or left for a period of time, the accumulated hydrogen gas inside it will be heated and released Or release slowly, and the manganese dioxide will be reduced and recovered, and the battery will be vigorous again!
