Abstract

We present a low-temperature synthetic route toward the binder-free MnO_x (the mixture of Mn₃O₄ and MnO₂)/single-walled carbon nanotube (SWCNT) macro-films, which could be employed as the single component of anodes in Li-ion batteries. Morphological characterizations reveal that the interconnected network of SWCNT macro-films in the free-standing MnO_x/SWCNTs intrinsically possesses high electrical conductivity and exhibits good mechanical adhesion on Cu foils (current collectors). The MnO_x nanoparticles directly grown onto the external surface of SWNT macro-films have very strong bonds with the nanotubes, avoiding agglomeration during their electrochemical operations. These MnO_x/SWNT macro-films are evidenced to possess an excellent capacity of ~1000mAhg^-1, showing promise as flexible anode materials for light weight and high performance Li-ion batteries.
