Synthesis and charecterization of LiMn1.5Ni0.5O4 by sol-gel method for cathode material & it's application in Li-ion battery.

Our past decade witness to the quick growth of Li-Ion battery industry in response to the growing needs of electronic and information industries. Lithium Cobalt Oxide used as Initial cathode material for Lithium batteries application it consist of high toxic nature, costly and with low energy density. Thus there need to develop new Li-Ion batteries to improve above characteristics along with efficiency and make it portable. So that can be used in electronics, transportation, and energy storage and especially in hybrid electric vehicles.LiMn_1.5Ni_0.5O₄ is hence the best development seen so far. It is improved version of LiCoO₂. It usually overcomes all the problem of older lithium batteries. The high initial capacity and good cycling behavior of LiMn_1.5Ni_0.5O₄ powders calculated at higher temperatures are closely related with the higher crystalinity and retention of the spinel structure with cycling and hence proved that LiMn_1.5Ni_0.5O₄ is far better than other batteries. For synthesizing LiMn_2-xNi_xO₄, we use sol-gel procedure. The electro chemical performances of prepared samples are tested. The crystalinity and lattice constants by X-Ray diffraction, thermal analysis by TGDTA, morphology by SEM and bonding between the atoms by FTIR were studied in this paper. [ABSTRACT FROM AUTHOR]
