I am impressed with this type of technologies’ advances, in fact as the time of the evolution of batteries cells is principal thanks improved by mining's science, the research of new ways how to obtain raw materials and by the discovery of new types of materials like Nano-technological supplies, with the time is more and more cheap create new industrial supplies and consumables, so due this in our word is developing new battery cells of bigger performance, autonomy, less size and weight, what does means this?, a final product which is capable of catch hold together with the economic growth of the Word in order to make himself auto-eco-sustainable.
