The investigation and development of flexible power sources has motivated the development of flexible, lightweight, binder-free electrodes for Li-ion batteries (LIBs). Here, we are proposing the fabrication of free-standing, flexible and foldable multi- walled carbon nanotubes (MWCNT)/lithium chrominum titanate (LiCrTiO4, LCT) composite buckypaper by a facile, scalable, cost-effective and environmental friendly tape casting method. LiCrTiO4 powder was synthesized through solid state reaction. The structural and morphological studies were conducted using various techniques such as X-ray diffraction, Raman spectroscopy, scanning and transmission electron microscopy. The LCT-MWCNT composite buckypaper is demonstrated as anode material for flexible LIBs and shows initial discharge capacity of ~158 mA h g-1, comparable to theoretical capacity of LiCrTiO4 at 1 C rate. Furthermore, an excellent cyclic stability with ~96% capacity retention was exhibited at 1C (100 cycles) and 10C (500 cycles) rate, which is mainly attributed to enhanced electric and ionic transport during electrochemical reactions.
