In-situ carbon-coated tin oxide (ISCC-SnO₂) was fabricated by colloidal processing and sucrose was used as a soluble carbon source. ISCC-SnO₂ was characterized by X-ray diffraction (XRD), Raman spectroscopy, and nitrogen adsorption–desorption by BET methods, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) properties of ISCC-SnO₂ were investigated in 1 M Na₂SO₄ solution. The specific capacitance of ISCC-SnO₂ was achieved 42.7 mFcm⁻² at a scan rate of 25 mVs⁻¹ and showed excellent charge–discharge behavior.

用于微型超级电容器的原位碳包覆氧化锡（ISCC-SnO 2）

通过胶体工艺制备了原位碳包覆的氧化锡（ISCC-SnO ₂），蔗糖被用作可溶性碳源。ISCC-SnO _2的特征在于X射线衍射（XRD），拉曼光谱，BET法，扫描电子显微镜（SEM）和透射电子显微镜（TEM）对氮的吸附-解吸。在1 M Na ₂ SO ₄溶液中研究了ISCC-SnO _2的循环伏安（CV）和恒电流充放电（GCD）特性。在25 mVs ^-1的扫描速率下，ISCC-SnO ₂的比电容达到42.7 mFcm ^-2，并表现出出色的充放电行为。
