With highly hydrophilic surfaces and superior metal conductivity, two-dimensional transition-metal carbides (MXenes) are highly valuable in the field of electrochemical energy storage. However, the easy stacking inclination of interlayers would lead to reduced ion accessibility and available transport paths within MXenes, thus limiting their electrochemical performance.
