Abstract

A study was performed to find the extent at which the carbon shell enables electrical contact among the CCVO particles, while not interfering with a smooth Li intercalation with the V2O3 particles. It was found that the carbon and hydrogen content in the CCVO samples was determined by elemental analysis measurement. The elemental analysis of the oxidation product showed that it contained only 0.17% of carbon that was much less than in the CCV2O3 product, owing to pronounced oxidation of the carbon. The study was mainly performed to find the use of CCVO as the active mass in composite cathodes for rechargeable lithium batteries. The CCV 2O3 product is a very important model material because it shows that the carbon coating allows smooth and reversible Li insertion into the V2O3 core.
