description |
Three different cathodes such as LiMn204, LiCo02 and Li2NigOlO were
synthesized by the sol-gel technique The said materials at low temperature were
achieved through the low temperature technique The X-ray diffraction study of the
compounds confirmed the formation of single-phase compound at higher calcination
temperature At low temperatures the X-ray diffractogram of the samples showed
the presence of low intensity diffraction lines with weak impurities indicating the
existence of crystallinity but these were not indexed to any kind of impurities of
LiMn20-+ LiCoOz and LizNisOlO The formation temperatures of the compounds
were analyzed using DTA. The DTA studies showed clearly the lowest formation
temperature and this formation temperature depends upon the gelating agent used 111
the present study The lowest formation temperatures recorded were 208°C for
LiMn20-+, 201°C for LiCo02 and 214°C for LjzNisOlO The thermogravimetric analysis showed that the compounds were stable up
to 800 °c The EDAX analysis was performed for the compounds to identify the
purity of the compounds The EDAX spectrum showed that there was no impurity
pI esent in the compounds It ascertained the formation of single-phase compounds
by XRD Because of low atomic weight lithium could not be detected other than
that the EDAX showed the presence of the respective atoms The particle size
distribution of the compounds showed that the particles were distributed in large
volume The particle diameter increased with the increase of calcination
temperature Grinding reduced the large volume distribution and the particle
diameter After grinding by mortar and pestle hand grinder, the particle size was
reduced much and the distribution was narrowed down, thereby the surface area of
the particle was increased
The SEM analysis also confirmed the sub-micron size reduction and the
distribution was narrowed down, thereby the surface area of the particle was
increased The compounds were used as electrode materials for lithium ion
batteries The battery analysis showed that the capacities of the LiMn20, LiCo02
and Li2NisOIO were 10 mAh , 24 mAh and 5 mAh respectively |
