Introduction to acid batteries
All batteries that use an acidic aqueous solution as an electrolyte are collectively referred to as an acid storage battery, and the most typical one is a lead-acid battery. The main advantages of the acid battery are high working voltage, wide operating temperature, good discharge performance at high and low rates, abundant raw materials and low price. The disadvantage is that the energy density is low, making it bulky and heavy.
Lead-acid battery, the positive electrode is lead dioxide, the negative electrode is sponge lead, the electrolyte is sulfuric acid aqueous solution, and the separator (separator) uses microporous rubber separator, microporous plastic separator or other materials according to different types of lead storage batteries. The housing is made of hard rubber, engineering plastic, fiberglass and other materials.
