What are the differences between general batteries and rechargeable batteries

Generally, batteries are primary batteries, non-rechargeable, common carbon batteries, alkaline batteries, and primary lithium batteries. The advantage is that they are cheap (relative to secondary batteries, which are actually not much cheaper), long storage time, and That is, the self-discharge is relatively low, and the weight is low and easy to carry. The disadvantage is that it is not rechargeable, and the cost of one-time use is high. Disposal will generally pollute the environment. It is suitable for electrical appliances with low power consumption and low current. Rechargeable batteries are secondary batteries. Commonly used are lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium batteries, and lithium iron phosphate batteries. The disadvantage is that they are expensive, and the matching charger is more expensive and heavier. Large, high self-discharge (the secondary lithium battery is relatively small, but it is still relatively large in relation to disposable lithium batteries). The advantage is that the uniform price is more affordable for repeated use, the discharge current is large, and it is suitable for appliances that are used more frequently and consume more power. To put it bluntly, the two complement each other. The disadvantage of the primary battery is the advantage of the secondary battery, and the advantage of the primary battery is the disadvantage of the secondary battery. However, the common point is that discarding will pollute the environment, but the degree is different. : Cheap, disadvantages: not reusable; advantages of rechargeable batteries: reusable, disadvantages: a bit expensive; the voltage of rechargeable batteries: 1.2V dry battery is a primary battery in the chemical power supply, 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. They are very easy to use. Storage battery is a kind of battery, and its purpose is to store limited electric energy and use it in suitable places. Its working principle is to convert chemical energy into electrical energy. It uses a lead plate filled with spongy lead as a negative electrode, a lead plate filled with lead dioxide as a positive electrode, and 22-28% dilute sulfuric acid as an electrolyte. When charging, electrical energy is converted into chemical energy, and when discharging, chemical energy is converted into electrical energy. When the battery is discharged, metallic lead is the negative electrode and undergoes an oxidation reaction and is oxidized to lead sulfate; lead dioxide is the positive electrode and undergoes a reduction reaction and is reduced to lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two poles respectively. After removing the power source, it returns to the state before discharge, forming a chemical battery. A storage battery is a battery that can be repeatedly charged and discharged, called a secondary battery. Its voltage is 2V, usually three batteries are connected in series, and the voltage is 6V. The car uses 6 batteries in series to form a 12V battery pack. The storage battery should be supplemented with sulfuric acid after a period of time to keep the electrolyte containing 22-28% dilute sulfuric acid.
