SnO2 quantum dots modified N-doped carbon as high-performance anode for lithium ion batteries by enhanced pseudocapacitance

SnO 2 is considered to be a promising candidate as anode material for lithium ion batteries, due to its high theoretical specific capacity (1494 mAh·g −1 ). Nevertheless, SnO 2 -based anodes suffer from poor electronic conductivity and serious volume variation (300%) during lithiation/delithiation p...
