fabrication and characterization of a new efficient limn1 / 3ni1 nanomateriau cathode k1 / 2 / 3, m4 for applications in lithium ion batteries based on standard materials

摘要

the invention relates to the manufacture of an oxide system, and its use as a nano material of cathode for lithium-ion battery (li ion). the oxide is a compound type nanoparticles limn4 / 3ni1 / 3co1 / 304, a spinel structure.the present invention relates to a process and the implementation of appropriate reagents are not standards, quality based and metal hydroxide carbonates and their direct use, despite the existence of specific impurities to provide a precursor and na nomatu00e9riau homogeneous with very good reproducibility of high purity, chemical and physical stability.
