| dc.description.abstract | The secondary lithium-ion battery has been widely used in various kinds of electrical and electronic devices, and is expected to be further spread into larger-sized applications such as power sources of hybrid automobiles. While cathode materials for secondary lithium-ion battery have been so far made mostly from lithium cobalt oxide, the development of substitute materials is essential because of the depletion and increasing prices of lithium and cobalt resources. The sodium-ion secondary battery is an alternative for lithium ion rechargeable battery utilizing mostly abundant sodium which has high electrochemical potential after the lithium. Therefore, in this study NaxMn(1_x)02 nano powder was synthesized by glycine nitrate combustion process (GNC) ,a low cost wet chemical method and electrical property variation was studied for different compositions of NaxMn(l-x)02 by changing the sodium to manganese ratio. DC four probe methods were used to investigate the electrical conductivity of prepared samples. The cathode of sodium-ion battery was fabricated on glass plates by spreading slurry made grinding sodium manganese oxide powder with PVDF, synthetic graphite, propylene carbonate and acetone. The conductivity of electrodes were measured by using Vander pauw method. Finally this study demonstrated that Na0.25M110.7502 composition having the highest electrical conductivity at room temperature of about 3.64*10-05 Scm-1 with compared to other compositions. | en_US |
