Advance in understanding of all-solid-state batteries

All-solid-state batteries, a battery design composed of all solid components, have gained attention as the next major advance beyond lithium ion batteries because of their potential to store more energy while being safer ...

Single-electrode material streamlines functions into a tiny chip

The ability to combine many functions into a single microchip is a significant advance in the quest to perfect the tiny, self-powered sensors that will expand the Internet of things. KAUST researchers have managed to combine ...

A new material for the battery of the future

Renewable sources of energy such as wind or photovoltaic are intermittent; production peaks do not necessarily follow the demand peaks. Storing green energy is therefore essential to moving away from fossil fuels. The energy ...

Taking charge: Researchers team up to make better batteries

A Florida State University and Cornell University research team found that batteries built from inexpensive and safe components can deliver three to four times the punch of batteries built with today's state-of-the-art lithium ...

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.
