A team of researchers at the University of California San Diego and the California-based company ZPower have developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than today’s state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured […]

A Technical University of Munich (TUM) team has reported it has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries. The team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at […]

University of California San Diego nanoengineers have developed a process for restoring spent cathodes to mint condition that could make it more economical to recycle lithium-ion batteries. The process is more environmentally friendly than today’s methods; it uses greener ingredients, consumes 80 to 90% less energy, and emits about 75% less greenhouse gases. The research […]

Oak Ridge National Laboratory (ORNL) researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics. The new family class named NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Scientists from Tokyo University of Science, Japan, have found an energy-efficient method to fabricate a hard carbon electrode with enormously high sodium storage capacity. The discovery could pave the way for next-generation sodium-ion batteries made with inexpensive and abundant materials, and having a higher energy density than lithium-ion batteries. Today, most rechargeable batteries are […]
