Improving high-energy lithium-ion batteries with carbon filler

Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible ...

Method to predict the atomic structure of sodium-ion batteries

Researchers from the Chinese Academy of Sciences and Delft University of Technology (TU Delft) have developed a method to predict the atomic structure of sodium-ion batteries. Until now, this was impossible even with the ...

Finland's battery plans spark environmental fears

Lines of trucks carrying piles of rock crisscross Finland's rugged Terrafame mine, which sits 300km (186 miles) below the Arctic Circle and is Europe's largest source of nickel for electric car batteries.

Battery (electricity)

In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type to store chemical energy and to deliver higher voltage or higher current than with single cells.

The battery cells create a voltage difference between the terminals of each cell and hence to its combination in battery. When an external electrical circuit is connected to the battery, then the battery drives electrons through the circuit and electrical work is done. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications, and is now a multi-billion dollar industry.
