Memory-effect-induced electrochemical oscillation of an Al-doped Li4Ti5O12 composite in Li-ion batteries

Abstract

Memory effects and electrochemical oscillation have recently been found in modified Li₄Ti₅O₁₂, but the correlation between these two phenomena has not been reported yet. Here, we found that these two phenomena could simultaneously occur in an Al-doped Li₄Ti₅O₁₂ composite, and the electrochemical oscillation can be controlled by regulating the memory effect.
