However, there are many challenges to be addressed which impede Ti<jats:sub>3</jats:sub>C<jats:sub>2</jats:sub>T<jats:sub><jats:italic>x</jats:italic></jats:sub> obtaining the ideal specific capacitance, such as restacking, re-crushing, and oxidation of titanium. Recently, many advances have been proposed to enhance capacitance performance of Ti<jats:sub>3</jats:sub>C<jats:sub>2</jats:sub>T<jats:sub><jats:italic>x</jats:italic></jats:sub>. In this review, recent strategies for improving specific capacitance are summarized and compared, for example, film formation, surface modification, and composite method. Furthermore, in order to comprehend the mechanism of those efforts, this review analyzes the energy storage performance in different electrolytes and influencing factors. This review is expected to predict redouble research direction of Ti<jats:sub>3</jats:sub>C<jats:sub>2</jats:sub>T<jats:sub><jats:italic>x</jats:italic></jats:sub> materials in supercapacitors.</jats:p>
