【 摘 要 】

Li2Na2Ti6O14was developed from Li5Ti4O12as a good active material for anode of the lithium battery. Li2Na2Ti6O14was prepared by a preliminary formation of Li2Na2Ti6O14through solid state reaction with calcination temperature at 700 °C, and sintering temperature at 800 oC for 8 hours. By analysis of XRD patterns, Li2Na2Ti6O14shows spinel structure which similar as Li5Ti4O12. Carbon coating on Li2Na2Ti6O14was done by using pyrolysis method at a temperature of 700 oC for 2 hours. The process of carbon coating was done under variation of comparison between Li2Na2Ti6O14and tapioca powder as a carbon source, i.e. 8:1, 10:1 and 12:1. The working voltage of Li2Na2Ti6O14/C product was 1,2 volt. The other analysis were conductivity, cyclic voltammeter, and charge - discharge.
