    Study Notes

    Battery Fundamentals

    • When the energy in a primary cell is used up, it cannot be replenished and the cell is discarded.

    Types of Batteries

    • Commercial batteries are designed for long-term use and can be recharged multiple times.

    Primary Cells

    • A primary cell is a type of battery that cannot be reused or recharged.

    Dry Cells

    • The most familiar type of dry cell is the alkaline battery.

    Battery Terminology

    • The term "battery" should not be used when referring to a single cell.

    Battery Components

    • The three basic components of all batteries are the anode, cathode, and electrolyte.

    Battery Functionality

    • The anode is the terminal that serves as the source of electrons that flow through an external electric circuit.

    History of Batteries

    • Alessandro Volta is credited with inventing the first battery in 1800.

    Electrolyte Function

    • The purpose of an electrolyte in a battery is to facilitate the flow of ions between the anode and cathode.

    Battery Operation

    • When connected to an external electric load, the function of a battery is to supply electrical energy to the load.
