Memory-effect-induced electrochemical oscillation of an Al-doped Li 4 Ti 5 O 12 composite in Li-ion batteries.

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.
