I. Different referents
1. Battery: after discharge, the internal active substance can be regenerated by charging to store electric energy as chemical energy; Chemical energy is again converted to electrical energy when it needs to be discharged.
2. Dry cell: A voltaic cell that USES an absorbent (such as wood chips or gelatin) to make the contents into a paste that does not spill.
Two, liugong loader parts different characteristics
1, battery: the use of external electrical energy to make internal active substances regeneration, the electrical energy storage for chemical energy, the need to discharge the chemical energy again into electrical energy output, such as life commonly used cell phone batteries.
2. Dry battery: Manganese-zinc battery, with a positive carbon rod between the middle channels, a mixture of graphite and manganese dioxide, and a fibrous network coated with a thick electrolyte paste, consisting of a solution of ammonium chloride and starch, with a small amount of preservatives; the outermost layer is a tube made of metal zinc skin, namely the negative electrode.
