Will lithium-air batteries ever take flight?

Amid growing climate concerns, many governments and scientists worldwide are trying to reduce air travel's environmental impact. Electric planes are a possible solution, but better batteries are needed to power large aircraft ...

Scientists develop a lithium-ion battery that won't catch fire

A flexible lithium-ion battery designed by a team of researchers from the Johns Hopkins Applied Physics Laboratory and built to operate under extreme conditions—including cutting, submersion, and simulated ballistic impact—can ...

Mitochondria work much like Tesla battery packs, study finds

For years, scientists assumed that mitochondria—the energy-generating centers of living cells—worked much like household batteries, generating energy from a chemical reaction inside a single chamber or cell. Now, UCLA ...

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.
