Abstract:SnO2, owing to its high theoretical capacity of 1378 mAh g-1 and low sodium insertion potential, is one of the attractive anode materials for Sodium-ion batteries (SIBs). However, extensive volume expansion (~300%), significant capacity loss, particle agglomeration, and low conductivity (1.82 x 10-8 S cm-1) of SnO2 limit its commercial applications. In this work, SnO2 nano-particles have been synthesized via a one-step hydrothermal method. Subsequently, 3D electrode architecture is developed using pitch-coated… Show more
