A team of Korean researchers has developed a processing technology for maximizing energy densities of high-capacity batteries. The joint research team, which consists of Dr. Minah Lee and Dr. Jihyun Hong of the Clean Energy Institute, Korea Institute of Science and Technology (KIST), have announced ......

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 counterparts (around 2,800 mAh per gram), and could thus theoretically ......

Rapid technological advancements in the electronics industry have led to a fast-growing market for high-performance wearable devices, such as smart bands and body-implantable electronic devices, such as pacemakers. These advancements have considerably increased the need for energy storage devices to......

Lithium polymer battery uses file alloy as positive electrode, polymer conductive material, polyacetylene, polyaniline or polyphenol as negative electrode, organic solvent as electrolyte. The specific energy of lithium polyaniline battery can reach 350w.h /kg, but the specific power is only 50-60W/......
