Memory effects and electrochemical oscillation have recently been found in modified Li 4 Ti 5 O 12 , 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 Li 4 Ti 5 O 12 composite, and the electrochemical oscillation can be controlled by regulating the memory effect. Electrochemical oscillation can be induced by regulating the memory effect of an Al-doped Li 4 Ti 5 O 12 composite in Li-ion batteries.
