2D nanostructures based on transition-metal diborides (TMDs) are theoretically predicted to possess an exceptionally high rate and long cycling stability for Li-ion storage owing to the intrinsic presence of boron honeycomb planes and multivalent transition-metal atoms. An international team of researchers (Japan, India) investigated the Li-ion storage potential of the TMD-based nanostructure–titanium diboride (TiB2)-based hierarchical nanosheets (THNS). They demonstrated that THNS can be utilized as a high-rate anode material for Li-ion battery (LIB) and that a high discharge capacity can be obtained at a current rate of 0.025 A g1– galvanostatic charge/discharge. They demonstrated that the THNS-based LIB anode can sustain extremely high current rates allowing ultrafast charging and considerable discharge capacity with a capacity retention of over 80% after 10 000 cycles… read more.
