What's the difference between dry battery and liquid battery?

Dry battery is a kind of voltaic battery. Some absorbents (such as sawdust or gelatin) are used to make the contents into a paste that will not overflow. It is often used as a power supply for flashlight lighting, radio, etc. After years of development, China's dry battery technology has made breakthroughs in specific energy, cycle life, high and low temperature adaptability and other issues. According to the data research center of Zhiyan, China is gradually narrowing the gap with the international leading technologies, reaching the international level in some core technologies, and entering the international market more and more. Dry battery is a kind of chemical battery that uses paste electrolyte to generate direct current (wet battery is a chemical battery that uses liquid electrolyte), which can be roughly divided into primary battery and secondary battery, and is a common portable battery in daily life. They can be used in many electrical appliances. Dry battery belongs to the primary battery in chemical power supply and is a disposable battery. Because the electrolyte of this chemical power supply device is a paste that cannot flow, it is called dry battery, which is relative to the battery with flowing electrolyte. Dry batteries are not only suitable for flashlights, transistor radios, tape recorders, cameras, electronic clocks, toys, etc. It is also suitable for national defense, scientific research, telecommunications, navigation, aviation, medicine and other national economic fields, and it is very easy to use. Ordinary dry batteries are mostly zinc-manganese batteries, with a positive carbon rod in the middle, a mixture of graphite and manganese dioxide outside and a layer of fiber mesh outside. If the battery works continuously or is used for a long time, manganese dioxide will be too late or close to saturation to be absorbed again, and the battery will lose its function because of too large internal resistance and too small output current. However, if the battery is heated or left for a period of time, the accumulated hydrogen will be released or slowly released due to heating. Manganese dioxide will also be reduced and recycled, and the battery will be full of vitality again.

A liquid battery consists of a battery in which an electrochemically active electrode is immersed in a glass container filled with electrolyte. Any battery, solid, liquid or solid-liquid combination battery, can only store chemical energy. In order to store chemical energy, any battery must be composed of three parts-anode electrode, cathode electrode and diaphragm between anode and cathode electrode. Most batteries, including those used in notebook computers, use solid materials such as zinc or lithium cobalt as cathode, graphite as anode and liquid salt solution as electrolyte membrane. On the other hand, this kind of liquid battery is different. Its cathode, anode and membrane are all liquids, and they are all hot molten liquids like mud.
