Electric battery
An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights , smartphones , and electric cars . [1] When a battery is supplying electric power , its positive terminal is the cathode and its negative terminal is the anode . [2] The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. [3] Historically the term "battery" specifically referred to a device composed of multiple cells, however the usage has evolved to include devices composed of a single cell. [4]

An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights , smartphones , and electric cars . [1] When a battery is supplying electric power , its positive terminal is the cathode and its negative terminal is the anode . [2] The terminal marked negative is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work. [3] Historically the term "battery" specifically referred to a device composed of multiple cells, however the usage has evolved additionally to include devices composed of a single cell. [4] |

An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode , and a negative terminal, or anode . The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. The terminal marked positive is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work. [1] Although the term battery technically means a device with multiple cells, single cells are also popularly called batteries. |

There are many types of electrochemical cells, including galvanic cells , electrolytic cells , fuel cells , flow cells , and voltaic cells . [1] Formally, an electrical "battery" is an array of similar voltaic cells ("cells") connected in series . However, in many contexts it is common to call a single cell a battery . [2] A battery's characteristics may vary due to many factors including internal chemistry, current drain, and temperature. |
