All batteries that use acidic aqueous solutions as electrolytes are collectively referred to as acid batteries, with the most typical being lead-acid batteries. The main advantages of acidic batteries are high working voltage, wide operating temperature, good discharge performance at high and low rates, abundant sources of raw materials, and low prices. Its disadvantage is that its energy density is low, resulting in a larger volume and weight. Lead acid batteries have a positive electrode of lead dioxide, a negative electrode of sponge like lead, and an electrolyte of sulfuric acid aqueous solution. The separator (separator) is made of materials such as microporous rubber separator, microporous plastic separator, or other materials according to different types of lead batteries. The battery shell is made of hard rubber, engineering plastic, fiberglass, and other materials
