Abatteryis a device consisting of one or moreelectrochemical cellswith external connectionsfor powering electrical devices such asflashlights,mobile phones, andelectric cars. Batteries come in many shapes and sizes, from miniature cells to huge battery banks. During the last few decades, environmental impact of the petroleum-based transportation infrastructure, along with the fear of peak oil, has led to renewed interest in an electric transportation infrastructure. The carbon footprint and other emissions of electric vehicles varies depending on the fuel and technology used for electricity generation. The electricity may be stored on board the vehicle using a battery, flywheel, or super capacitors. Hence the development of different type of battery power EV started. Aluminium–air batteries(Al–air batteries) produce electricity from the reaction ofoxygenintheairwithaluminium.
