| Abstract: | Intercalation of ions between the adjacent MXene layers can change the interlayer environment and influence the electrochemical ion storage capacity. In order to understand the effect of multi-ions confined by the MXene layers on the performance of electrochemical energy storage, Co2+, Mn2+ and Ni2+ intercalated into Ti3C2Tx MXene which already pre-intercalated Al3+ are obtained by spontaneous static action. Based on the monitor of (002) crystal orientation, intercalated multi-ions can regulate and control the interlayer environment of MXenes via stress, which induces lattice shrinkage occurring in the c axis. Limited by ion storage mechanism-performance, the multi-ion occupies the interspace of MXene and affects the electrochemical performance. This work would offer guidance to understand the relationship among the multi-ion and MXene by two-dimensional (2D) layered materials. |
