It generates current when your fingertips touch the keys, which are coated with an electrode material.

当你的手指触摸按键，涂有电极材料的这种键盘会产生电流。

The new electrode material could also be used with solid rather than liquid electrolytes, to make " solid-state" batteries.

这种新的电极材料也可以用于固体电解质(非液体电解质)以制造“固态”电池。

Thus far, innovation on inactive components has mostly focused on shrinking them down, so that more electrode material can fit in the cell.

到目前为止， 非活性组件的创新主要集中于将其缩小，以便更多的电极材料能够装入电池中。
