　　Primary battery

　　The primary battery is the primary battery, which has an obvious feature that it cannot be charged and will be discarded when used up. It also has a name called dry battery. The common disposable batteries are zinc manganese dry cells and magnesium manganese dry cells. It is mainly used in civil fields, such as remote control, toy cars, etc. The ordinary zinc manganese dry battery is one of the upgrading products of the civilian battery, which is generally replaced by the alkaline zinc manganese battery with better performance.

　　Secondary battery

　　The secondary battery is also called rechargeable battery (storage battery). Unlike the primary battery, it can be used for charging cycle. The most common secondary battery is the lead battery, which is composed of two groups of grid plates arranged alternately. The positive plate is covered with PbO2, the negative plate is covered with Pb, and the electrolyte is H2SO4 solution. Now the battery in mobile phones is called lithium battery, which is also a kind of secondary battery.
