摘要

The production of 3C products in electronics information and communication has now been oriented toward wireless and portable electronic devices. Therefore the high performance components of the product are designed to be "lighter, thinner, short, smaller". For this reason urgent demand exist for secondary batteries that are more compact, lighter and higher energy density. The second big market of lithium batteries will be the electrical bikes and electrical cars. The battery industry requires the integration of various technologies in the field of chemistry, material science, know-how, etc. The continuous development on the theoretical side and furthermore a long period of experience in R&D groups are also needed. The market demands products to be lighter, reliable, with higher electric power capacity and improved safety design. The commercially available rechargeable lithium batteries refers to the Li-Ion battery which uses carbon powder as negative active electrode material and lithiated metallic oxides as cobaltate and nickelate for positive active electrode material. For the moment only LiCoO_2 (lithium cobaltate) as positive electrode material occupies the market. However, the cost of LiCoO_2 material is so high that it would take up too much of the battery cost and besides, its specific energy density is not the highest, therefore, it may be replaced by the concurrent LiNiO_2- The price of LiNiO_2 material is less expensive with the highest specific gravimetric capacity, but it is difficult for synthesis and treatment. Both materials are not environmentally friendly.
