TLDR
An in situ reduction method is developed to synthesize SnO2 quantum dots@graphene oxide by the oxidation of Sn(2+) and the reduction of the graphene oxide, resulting in a capacity retention of 86% even after 2000 cycles.Abstract:
Tin-based electrode s offer high theoretical capacities in lithium ion batteries, but further commercialization is strongly hindered by the poor cycling stability. An in situ reduction method is developed to synthesize SnO2 quantum dots@graphene oxide. This approach is achieved by the oxidation of Sn(2+) and the reduction of the graphene oxide. At 2 A g(-1), a capacity retention of 86% is obtained even after 2000 cycles.read more
