In this work, the tin dioxide/reduced graphene oxide (SnO₂/rGO) hybrid with 3D porous architecture has been prepared by a straightforward and environmentally friendly one‐step solvothermal method, in which superfine SnO₂ nanoparticles are well‐proportioned immobilized on rGO. When applied as anode material for lithium‐ion batteries (LIBS), the prepared SnO₂/rGO hybrid demonstrates superior electrochemical properties. It can be achieved high initial cycle reversible capacity of 1058 mA h g⁻¹ and retained a stable discharge capacity of 1104 mA h g⁻¹ after 200 cycles at 0.1 A g⁻¹. Remarkably, a high capacity of 750 mA h g⁻¹ can be kept after 500 cycles at 0.5 A g⁻¹. These consequences manifest that the obtained SnO₂/rGO hybrid is a promising anode material for LIBS.

高性能锂离子电池的一步溶剂热法将超细SnO2均匀固定在还原的氧化石墨烯板上

在这项工作中，通过直接且环保的一步溶剂热法制备了具有3D多孔结构的二氧化锡/还原氧化石墨烯（SnO ₂ / rGO）杂化体，其中超细SnO ₂纳米颗粒均匀地固定在rGO上。用作锂离子电池（LIBS）的负极材料时，制得的SnO ₂ / rGO杂化物表现出优异的电化学性能。可以实现1058 mA hg ^-1的高初始循环可逆容量，并在0.1 A g ^-1下200次循环后仍保持1104 mA hg ^-1的稳定放电容量。显着的750 mA hg ^-1的高容量可以在500次循环后在0.5 A g ^-1下保持。这些结果表明，所获得的SnO ₂ / rGO杂化物是有希望的LIBS阳极材料。
