This conductivity enhancement facilitates efficient charge transport within the electrode, leading to improved performance in energy storage devices [102, 103]. The high surface area of MXene allows for a higher quantity of active sites available for charging/discharging, resulting in enhanced energy storage capacity.
In particular, attention is paid to applications in electrochemical energy storage, such as supercapacitors, batteries, and their flexible components. MXenes and related composites are well suited for use in EES because of their exceptional characteristics, distinct morphologies, and layered structures.
MXene materials offer a wealth of attributes that address critical challenges in energy storage, and their ongoing exploration holds promise for revolutionizing the field and enabling the development of more efficient, durable, and safer energy storage devices.
