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 ...
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 ...

(Phys.org)—In order to prevent short circuits in batteries, porous separator membranes are often placed between a battery's electrodes. There is typically a tradeoff involved, since these separators must simultaneously ...
Scientists have developed a new technique that can print batteries on almost any surface, which is expected to be essential for future flexible electronics such as roll-up displays, smart electronic clothing, and Google Glass-type ...
(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion ...
(Phys.org) —Graphene has already been demonstrated to be useful in Li-ion batteries, despite the fact that the graphene used often contains defects. Large-scale fabrication of graphene that is chemically pure, structurally ...
(Phys.org) —It was a big week for scientists studying the cosmos as a radio-burst discovery deepens astrophysics mystery—a very short burst of radio waves indicates a mysterious pulse came from the outer regions of space. ...
(Phys.org) —If the recently released Google Glass and soon-to-be-available Apple iWatch are any indication, wearable electronics may be the next big wave of the future. Although they offer some cutting-edge features, from ...
(Phys.org) —While there has been much research lately on the development of flexible electronic devices that can be integrated into clothes, glasses, watches, and even skin, the limiting factor of this technology is the ...
