The Anatomy of a Battery - American Chemical Society
Batteries are made up of two parts. One part, the anode, “holds on” to its electrons very loosely. The other part is the cathode, and it has a strong pull on the electrons and holds them tightly. Electricity is generated when electrons move from the anode (– end) to the cathode (+ end).

Jul 18, 2023 · Take a look at any battery, and you'll notice that it has two terminals. One terminal is marked (+), or positive, while the other is marked (-), or negative. In normal flashlight batteries, like AA, C or D cell, the terminals are located on the ends.
Electric battery - Wikipedia
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.

DOE Explains...Batteries | Department of Energy
Batteries consist of two electrical terminals called the cathode and the anode, separated by a chemical material called an electrolyte. To accept and release energy, a battery is coupled to an external circuit. Electrons move through the circuit, while simultaneously ions (atoms or molecules with an electric charge) move through the electrolyte.
A Li-ion battery is composed of the active materials (negative electrode/positive electrode), the electrolyte, and the separator, which acts as a barrier between the negative electrode and positive electrode to avoid short circuits.
