The difference between 18650 lithium battery and general dry battery.

The difference between 18650 lithium battery and general dry battery.

Little knowledge, although the difference between lithium batteries and dry batteries is one word, they are completely different things.

Lithium batteries can be reused multiple times, while dry batteries are disposable products and cannot be repeatedly charged and discharged.

Working principles of lithium batteries and dry batteries
1. Lithium battery: After discharge, the internal active materials can be regenerated through charging, storing electrical energy as chemical energy. When discharging is required, chemical energy can be converted back into electrical energy. It belongs to rechargeable batteries that can be recycled multiple times, also known as secondary batteries;

2. Dry battery: It is a type of photovoltaic battery and a disposable battery. It uses a certain amount of absorbent to make the contents into a paste that will not overflow;

Characteristics of lithium batteries and dry batteries
1. Lithium battery: When charging, external electrical energy is used to regenerate internal active materials, and the electrical energy is stored as chemical energy. When discharging, the chemical energy is converted into electrical energy and output again, such as mobile phone batteries;

2. Dry battery: Mn Zn battery, with a positive carbon rod in the middle, a mixture of graphite and manganese dioxide on the outside, and a thick layer of fiber mesh coated with electrolyte paste. The electrolyte paste is composed of ammonium chloride solution, starch, and a small amount of preservative. The outermost layer is a tube made of metal zinc skin, which is the negative electrode;

Summary; The working principles, characteristics, and uses of the two types of batteries are also different. Lithium batteries convert their electrical energy (discharge) and chemical energy (charge) from internal active materials, while dry batteries use absorbents to convert their contents into paste like substances to generate electrical energy.
