Mar 28, 2024 · Batteries power our lives by transforming energy from one type to another. Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops, and cars), a battery stores chemical energy and releases electrical energy.
May 9, 2021 · What Are Batteries and How Do They Work? Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources.

Historically, the word "battery" was used to describe a "series of similar objects grouped together to perform a function," as in a battery of artillery. In 1749, Benjamin Franklinfirst used the term to describe a series of capacitors he had linked together for his electricity experiments. Later, the term would be used for any electrochemical cells...
One fateful day in 1780, Italian physicist, physician, biologist, and philosopher, Luigi Galvani, was dissecting a frog attached to a brass hook. As he touched the frog's leg with an iron scapel, the leg twitched. Galvani theorized that the energy came from the leg itself, but his fellow scientist, Alessandro Volta, believed otherwise. Volta hypoth...
William Cruickshankof Scotland solved the leakage problem by laying the voltaic pile on its side to form the "trough battery." The second problem, short life span, was caused by the degradation of the zinc due to impurities and a build up of hydrogen bubbles on the copper. In 1835, William Sturgeondiscovered that treating the zinc with mercury woul...
In 1859, the French physicist Gaston Plantécreated a battery using two rolled sheets of lead submerged in sulfuric acid. By reversing the electrical current through the battery, the chemistry would return to its original state, thus creating the first rechargeable battery. Later, in 1881, Camille Alphonse Faureimproved Planté's design by forming th...
Up until the late 1800s, the electrolyte in batteries was in a liquid state. This made battery transportation a very careful endeavor, and most batteries were never intended to be moved once attached to the circuit. In 1866, Georges Leclanché created a battery using a zinc anode, a manganese dioxide cathode, and an ammonium chloridesolution for the...
In the 1970s, COMSAT developed the nickel-hydrogen battery for use in communication satellites. These batteries store hydrogen in a pressurized, gaseous form. Many man-made satellites, like the International Space Station, still rely on nickel-hydrogen batteries. The research of several companies since the late 1960s resulted in the createion of th...
Jun 12, 2024 · battery, in electricity and electrochemistry, any of a class of devices that convert chemical energy directly into electrical energy. Although the term battery, in strict usage, designates an assembly of two or more galvanic cells capable of such energy conversion, it is commonly applied to a single cell of this kind.

Feb 13, 2024 · A battery is a self-contained, chemical power pack that can produce a limited amount of electrical energy wherever it's needed.
Feb 25, 2016 · A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
