| dc.description.abstract | Note: See the PDF Version Lithium-ion battery (LIB) is a family of rechargeable battery types in which the lithium ions move from the negative electrode to the positive electrode through the electrolyte. LIBs are currently one of the most popular types of battery for portable electronics with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. However, the present generation of LIBs has many limitations, such as high internal resistance, expensiveness, temperature effect, aging effect, short circuiting, and environment effect and overheating. The present inferior electrode materials are the main reason for these drawbacks and hence the main obstacle to achieve reliable and cheaper lithium-ion batteries (Pushpaka et al., 2008). This abstract presents a study of developing Li (Ni1i3Co1j3Mn1n) 02 based cathode electrodes and NiO-LiFe02-LiCo02 based anode electrodes with the Sri Lankan graphite as electrical conductivity enhancer. These novel electrode materials were synthesized by using Glycine-nitrate and Pechini methods, which are low cost techniques but can result in powders with high purity, homogeneity and particle morphology that are highly desired for LIB electrodes (Wijayasinghe et al., 2006). On the other hand, the expensive synthetic carbon materials are now being used as electrical conductivity enhancer of LIB electrodes, currently. In a recent research work on Sri Lankan graphite at the Uva Wellassa University with the collaboration of Institute of Fundamental Studies our group indicated of having sufficient electrical conductivity in Sri Lankan graphite to be used as conductivity enhancer (Geethika et al., 2010). Sri Lanka has been well known for processing high purity graphite, which is mainly being exported as cheap raw materials. Introducing this cheaper material for the high-tech energy conversion devices will definitely reduce the cost of these devices while also adding value to our mineral resources. By considering these factors, Sri Lankan Bogala graphite was investigated in this study as a conductivity enhancer in LIB electrodes. | en_US |
