Alkali-induced crumpling of Ti3C2Tx(MXene) to form 3D porous networks for sodium ion storage

We present a novel strategy for constructing three-dimensional (3D) porous Ti3C2Tx (MXene) networks by alkali-induced crumpling of Ti3C2Tx nanosheets. The 3D porous Ti3C2Tx networks display high capacity and outstanding rate performance as anode materials for sodium-ion batteries.
