基于种子辅助水热生长法合成了由接枝在石墨烯上的碳包覆二氧化锡纳米棒组成的三明治结构，先形成石墨烯负载的二氧化锡纳米棒，随后进行纳米碳包覆。作为一种用于高功率和高能量应用的潜在负极，这种分级纳米结构由于其先进的结构特性，展现出极大增强的协同效应，具有高达1419毫安时每克的极高储锂能力。
Sandwiched structures consisting of carbon coated SnO2 nanorod grafted on graphene have been synthesized based on a seed assisted hydrothermal growth to form graphene supported SnO2 nanorods, followed by a nanocarbon coating. As a potential anode for high power and energy applications, the hierarchical nanostructures exhibit a greatly enhanced synergic effect with an extremely high lithium storage capability of up to 1419 mA h g(-1) benefiting from the advanced structural features.
