Lead-acid batteries are made up of several components, each of which plays a critical role in the battery’s operation:
Lead Electrodes: The negative electrode is made of pure lead, while the positive electrode is made of lead dioxide.
Sulfuric Acid Electrolyte: The electrolyte, which is a solution of sulfuric acid and water, contains the ions necessary for the electrochemical reactions.
Separators: Separators are made of a porous material that keeps the lead electrodes from touching each other, preventing short-circuiting.
Plastic Container: The plastic container houses the electrolyte and prevents spills.
Terminal Connectors: The terminal connectors are used to connect the battery to external devices.
