Printing atom by atom: Lab explores nanoscale 3D printing

It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into ...

New strategy proposed for ultra-long cycle lithium-ion battery

In recent years, lithium-ion batteries have been widely used in many fields. Compared with traditional lithium ion battery cathode materials, more lithium ions in lithium-rich manganese-based cathode materials of unit mass ...

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.
