Relevant information about car batteries is as follows: 1. Introduction: A car battery, also known as a storage battery, is a type of battery. Its working principle is to convert chemical energy into electrical energy. Usually, what people refer to as a battery is a lead-acid battery, which is mainly made of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Working Principle: It uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and a 22-28% dilute sulfuric acid solution as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.
