An alternating stack (SG/GN) consisting of SnO₂-functionalized graphene oxide (SG) and amine-functionalized GO (GN) is prepared in solution. The thermally reduced SG/GN (r(SG/GN)) with decreased micro-mesopores and completely eliminated macropores, results in a high reversible capacity and excellent capacity retention (872 mA h g⁻¹ after 200 cycles at 100 mA g⁻¹) when compared to a composite without GN.
一种由 SnO₂功能化氧化石墨烯 (SG) 和胺功能化 GO (GN) 组成的交替堆叠 (SG/GN) 是在溶液中制备的。与不含 GN 的复合材料相比,具有减小的微孔和完全消除大孔的热还原 SG/GN(r(SG/GN)) 具有高的可逆容量和优异的容量保持率(在 100 mA g⁻¹ 下 200 次循环后为 872 mA h g⁻¹)。
