• All-pseudocapacitive and highly deformable MXene hybrid film is successfully fabricated by a facile and efficient vacuum-assisted filtration of ultrathin MoO₃ nanobelts and delaminated MXene nanosheets.

• The optimal M/MoO₃ hybrid electrode delivers an ultrahigh volumetric capacitance of 1817 F cm⁻³ (545 F g⁻¹), which exceeds large majority of previously reported MXene-based flexible electrodes.

• The symmetric supercapacitor presents excellent energy density of 44.6 Wh L⁻¹ (13.4 Wh kg⁻¹), indicating the electrode promising in achieving high-energy-density devices.
