SnO2 has been studied as a promising candidate for anode material of lithium-ion batteries owing to its high theoretical capacity. However, low conductivity and large volume expansion of SnO2 during repeated cycles significantly limit its practical applications. One of the most strategies to overcome the limits of the SnO2 is incorporation of graphene to limit aggregation of particles and improve cycle performance by mitigating the volume expansion. In this work, we synthesized SnO2/nanoperforated graphene microball which is a unique design of SnO2/graphene structure with nanoperforations located under the SnO2 to analyze the effect of nanoperforations on the electrochemical activity of SnO2 or the lithium/sodium–ion storage performance. More details will be discussed at the meeting.
