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.
A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
Electrochemical cell, a device which produces electricity through chemical reactions, commonly referred to as a battery; Solar cell, a device which produces electricity from sunlight; Electrolytic cell, a device which decomposes chemical compounds through electrolysis; electric cell can convert chemical energy into electrical energy
Light: Energy produced by light being absorbed by photoelectric cells, or solar power. Chemical: Energy produced by chemical reaction in a voltaic cell, such as an electric battery. Pressure: Energy produced by compressing or decompressing specific crystals. Magnetism: Energy produced in a conductor that cuts or is cut by magnetic lines of ...
A secondary cell produces current by reversible chemical reactions (ex. lead-acid battery car battery) and is rechargeable. Lead-acid batteries are used in an automobile to start an engine and to operate the car's electrical accessories when the engine is not running. The alternator, once the car is running, recharges the battery.

Juan Soto watches his solo home run in Game 2 of the 2024 World Series at Dodger Stadium. He hit .327 this past postseason for the Yankees with four homers, nine RBI and a 1.102 OPS in 14 games.
The lead–acid battery was the first practical secondary (rechargeable) battery that could have its capacity replenished from an external source. The electrochemical reaction that produced current was (to a useful degree) reversible, allowing electrical energy and chemical energy to be interchanged as needed.
