Principles of battery

  • What is battery?

    • Device that converts the chemical energy generated through the chemical reactions, which are one of the unique characteristics of all the substances that exist in the nature, into electrical energy to be used for various purposes.
  • What is lead storage battery (Lead-Acid Battery)?

    • It is a battery composed of lead and dilute sulfuric acid. When negative electrode (Pb) and positive electrode (PbO2) are immersed in the electrolyte (H2SO4) to form circuit, electrical potential is generated through chemical reaction.
  • Key functions of the battery (Main Functions of Battery)

    • Starting [Ignition] : Functions to start automobile (ignition of engine)
    • Lighting : Functions to start automobile (ignition of engine)
    • Ignition : Supply electric power necessary for ignition coil, etc.
