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 ...

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) —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) —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 ...
(Phys.org)—The world of rechargeable batteries is full of trade-offs. While lithium-ion (Li-ion) batteries are currently the most commercially successful, their low energy density doesn't allow for a long driving range. ...
(Phys.org) -- As their name suggests, Li-air batteries use air to operate, pulling out oxygen molecules to use in a porous, carbon-based cathode, while using lithium in the anode. Because using air means the battery doesn’t ...
(PhysOrg.com) -- It has all the appearances of a breakthrough in battery technology, except that it’s not a battery. Researchers at Nanotek Instruments, Inc., and its subsidiary Angstron Materials, Inc., in Dayton, Ohio, ...
In a vivid demonstration of the progress being made in miniaturizing energy storage devices, a team of engineers from Rice University in Houston, Texas, has fabricated an energy storage device where all essential components ...
