QCM and Electrochemical Studies of Li Intercalation in V6O13
Abstract
Simultaneous electrochemical and quartz crystal microbalance measurements were used to study the intercalation of Li+ into V6013. It was found that at low to modest concentrations of the intercalant, the stoichiometry of the reaction is simple metal ion insertion, and the measured mass (QCM) is equal to the mass (charge) calculated from the charge passed. At higher concentrations, the ratio of mass (QCM)/mass(charge) is larger than one, and suggests complexities such as changes of morphology and the formation of second phases. (Author) (TTL)
