【摘要】 用电化学腐蚀反应制得多孔硅材料,将多孔硅材料作为正电极与锂片组装成扣式半电池。对制得的半电池分别进行恒流充放电测试与循环伏安特性测试,观测得到锂离子在多孔硅材料中有可逆的嵌入和脱嵌行为。更多还原

【Abstract】 Galvanic corrosion reaction was used to prepare porous silicon, which was applied as the anode electrode. Combined it with lithium film to make up a button cell. After constant current testing in the performance of charge and discharge and cycle testing of relationship between voltage and current, it was observed that lithium ion had a reversible behavior of insertion and extraction in porous silicon.更多还原
