Can't Pull Out the Key When the Whole Car Loses Power?

[Harley]

Cannot pull out the key when the whole car loses power. Below is relevant information about car batteries: 1. Concept: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, what people refer to as a battery is a lead-acid battery. That is, a battery mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Working Principle: It uses a lead plate filled with sponge-like lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 22~28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead is the negative electrode, undergoing an oxidation reaction and being oxidized to lead sulfate; lead dioxide is the positive electrode, undergoing a reduction reaction and being reduced to lead sulfate.
