A new study by researchers at Lanzhou University and Hubei University proposes a quantum battery (QB) charging scheme based on a rectangular hollow metal waveguide. This approach allows them to overcome environment-induced ...
Conductive polymers, synthetic substances with large molecules that can conduct electricity, can have a broad range of valuable applications. For instance, they have been used to create sensors, light-emitting diodes, photovoltaics ...
While flexible and stretchable electronics technologies have progressed in leaps and bounds over the past 10 years, batteries to power them have some catching up to do. Researchers in Singapore and China have now demonstrated ...
Most existing lithium-ion batteries (LIBs) integrate graphite anodes, which have a capacity of approximately 350 milliamp hours (mAh) per gram. The capacity of silicon anodes is almost 10 times higher than that of their graphite ...

While batteries have been improving in recent times, at their core today's batteries still operate on the same basic electrochemical principles developed in the 18th and 19th centuries. Some physicists are now wondering whether ...
By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires ...
(Phys.org)—Tannins may be best known for their presence in red wine and tea, but in a new study researchers have demonstrated for the first time that tannins from tree bark can also serve as battery cathode materials. As ...
(Phys.org)—Researchers have fabricated rechargeable batteries by using highly conductive yarns that have a diameter and flexibility similar to that of a piece of cotton yarn. The new yarn battery can be woven into fabric ...
(Phys.org)—Scientists have used sugar cubes as a template for synthesizing stretchable battery electrodes, which serve as a key component in newly designed stretchable yet mechanically robust sodium-ion batteries. Although ...
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.
