Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Dianci bileiqi, 2012 电网电压谐波不仅对MOA泄漏电流中的容性分量带来干扰,而且对阻性分量也带来干扰。分析了电压谐波对两种基本方法-补偿法与谐波分析法的影响,并对补偿法进行了仿真计算,补偿法必须考虑容性谐波的干扰,谐波分析法避开了容性谐波的干扰,两种方法都不能消除阻性电流中直接来自电压谐波中的分量,综述目前已有消除电压谐波影响的方法,可根据阻性电流基波分量计算出阻性电流值及谐波分量,阻性电流中来自系统电压谐波干扰部分的消除还需进一步分析。
