Electrochemical oscillation during galvanostatic charging and discharging of Zr-modified Li₄Ti₅O₁₂ in Li-ion batteries.

ABSTRACT: The electrochemical oscillation in Li-ion batteries has been reported for two-phase electrode materials of Li₄Ti₅O₁₂ and LiCrTiO₄, which is originated from the group-by-group phase transition in a multi-particle electrode. For both Li₄Ti₅O₁₂ and LiCrTiO₄, the electrochemical oscillation exhibits usually during charging, while rarely for discharging. Herein, a series of Zr-modified Li₄Ti₅O₁₂ samples are prepared by using the spray-drying combined with high-temperature sintering method, and the electrochemical oscillation is observed during not only the charging process, but also the discharging process, which gradually grows up and then disappears by increasing the Li con
