Hollow Nano Spheres for Lithium-ion Batteries

Abstract:Technology in the Twentieth century requires miniaturization of devices into nanometer sizes while their ultimate performance is dramatically enhance. This raises many issues regarding to new materials for achieving specific functionality and selectivity. Nanomaterials a new branch of materials research are attracting a great deal of attention because of their potential applications in areas such as Electronics. There are two ways of approaching the properties of nanoscale objects: the bottom-up approach and the top-down approach. In the first, one assembles atoms and molecules into objects whose properties vary discretely with the number of constituent entities, and then increases the size of the object until this discretisation gives way in the limit to continuous variation. The relevant parameter becomes the size rather than the exact number of atoms contained in the object. In the second case, one considers the evolution of the properties of a sample as its size is whittled down from macroscopic toward nanometric lengths. It is this approach that we shall examine here, whilst mentioning zones of overlap and exclusion between the two approaches. Nanomaterials plays a very important role in various applications. One of the best applications of Nanomaterials is for Energy Storage Applications. Since the surface reactivity increases in Nano dimensions, their structures play a very important role under these dimensions. The Nanoparticles shape and morphology can also help to improve the performance of the devices. This paper mainly deals with the importance of Nanoparticles, particularly Hollow Nanospheres helps the movement of ions to circulate between the hollow spaces and to act as a transport media for the ions. Various methods are adopted for the synthesis of Hollo
