||Recently, numerous research has been reported that electrode composed of MXene shows superior electrical performances. Since MXene presents high electrical conductivity, high structural stability, and moderate capacity, it is one of the promise materials for energy storage devices such as Li-ion battery and Na-ion battery. However, as-deposited MXene film does not show the high performance because MXene is a stacked 2-D material. It has been reported in the literature that high energy density of the film is observed when using 3-D hollow structure. Inspiring from research, in this study, we have investigated the specific capacity and lithium-ion conductivity in various films made of 3-D MXene hollow shells. To adjust sizes of the hollow shell, we have used various sizes of PMMA particles and coated the particles surfaces by MXene film, and followed by sintering to fabricate the hollow shell.
