我们创造了一种独特的 SnO2-石墨烯双气凝胶 (SnO2/GDA) 纳米复合材料，具有精致的锂和钠离子电池负极性能（LIB、NIB NAB SIB）。同时，我们采用电化学方法，首次分析了转化反应 (SnO2 + 4Li(+)+4e(-) Sn + 2Li(2)O) 与合金化反应 (Sn+xLi(+)+xe(-) LixSn, x 从动力学控制到扩散控制的转变。
We created a unique SnO2-Graphene Dual Aerogel (SnO2/GDA) nanocomposite with exquisite lithium and sodium ion battery anode performance (LIB, NIB NAB SIB). In parallel we employed electrochemical methods to be the first to analyze the transition from kinetic control to diffusion control for the conversion reaction (SnO2 + 4Li(+)+4e(-) Sn + 2Li(2)O) vs. for the alloying reaction (Sn+xLi(+)+xe(-) LixSn, x
