Spinel lithium titanate (LTO) possesses high working voltage, stability, safety, and negligible volume change, while it suffers from low electronic conductivity that limits rate performance at large current densities. 2D Mxenes have recently drawn attention to various applications due to high conductivity, large surface area, flexibility, and polar surface benefits.
