An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor , which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
On average, a motor for an electric car has about 20 moving parts, but a comparable ICE would have 200 or more. [9] Some electric vehicles motors are permanent magnet motors that require rare-earth elements such as neodymium and dysprosium. Production of these materials is also dominated by China and poses environmental problems.
The combined global production capacity in 2023 reached almost 2000 GWh with 772 GWh used for EVs in 2023. Most production is based in China where capacities increased by 45% that year. [1]: 17 With their high energy density and long cycle life, lithium-ion batteries have become the leading battery type for use in EVs. They were initially ...

About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.
As a result, costs for thin-film solid-state batteries become prohibitive in consumer-based applications. It was estimated in 2012 that, based on then-current technology, a 20 Ah solid-state battery cell would cost US$100,000, and a high-range electric car would require between 800 and 1,000 of such cells.

The Roadster was the first highway-legal all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 320 km (200 miles) per charge. [ 46 ] Better Place , a venture-backed company based in Palo Alto, California , but steered from Israel , developed and sold battery charging and battery ...
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.
