The new material has such high energy density because it can operate at a higher voltage than current electrode materials and also store more lithium ions.

这种新材料具有高能量密度，因为它能够以比目前更高的电压的电极材料储存更多的锂离子个单一的百分比数字。

This forces the freed electrons to travel to the second electrode through a wire, creating an electric current.

而自由电子则通过一条导线移动至第二电极，从而产生电流。
