最近投了一篇文章，具体做锂电正极材料的，两个审稿人意见都很正面积极，其中一个审稿人的意见中，有一条的意思本人不是太明了，请版上的大神帮忙看看，感谢！
审稿意见：How much is the voltage??hysteresis between charge and discharge ? The author shows at least??mention this or may show a figure showing a typical hysteresis and calculating the round trip efficiency.
这条审稿意见针对的图如附件所示
How much is the voltage??hysteresis between charge and discharge指的是电压滞后，How much这个量化应该怎么回复？The author shows at least??mention this or may show a figure showing a typical hysteresis and calculating the round trip efficiency. 这句话具体什么意思，showing a typical hysteresis这个怎么弄？要求计算round trip efficiency，这个循环效率具体指什么，这个貌似没听说锂电电极材料中循环效率这一说法，请大神解答，非常感激？
