We report on the intercalation of Li+, Na+, Mg2+, K+, NH4+, and Al3+ ions between the 2D Ti3C2Tx layers. In most cases, the cations intercalated spontaneously.  The intercalation of some ions, notably Al3+, can be promoted electrochemically. We also report on intercalation-induced high capacitance of flexible Ti3C2Tx paper electrodes in aqueous electrolytes.
