Energy storage technology


Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is generally called an accumulator or battery

The role and utilization of pseudocapacitance for energy storage by supercapacitors
free download

The principle of utilizing the non-Faradaic double-layer capacitance of electrode interfaces as a means of storinc electrical energy was suggested and utilized in technologies initiated some 37 years ago. However, only over the last ten years has major interest been Energy is necessary for a number of reasons; the most basic and obvious involve the preparation of food and the provision of heat in order to make life comfortable, or at least, bearable. Subsequently, a wide range of technological uses of energy have emerged and
