摘要：
To improve the performance of lithium-ion batteries, a facile micro-arc oxidation process to synthesize SnO2 is developed with graphene used as a conductive additive. The integration of the current collector and the active substance is realized by the simplified method. As a result, the designed material exhibits an outstanding energy capacity up to 482 mAh/g at current density of 1.0 C after 200 cycles and a good rate performance of 746 mAh/g at current density of 0.2 C. This work provides a starting point for preparation of other metal oxides by micro-arc oxidation for lithium storage applications.
