这种电极可以在4000此循环充电后继续维持83%的能源，仍可在用，而相比之下，蓄电池只能循环充电几百次，锂离子电池可以循环1000次。

The electrodes maintain 83 percent of their charge capacity after 40, 000 cycles-in comparison, lead-acid batteries last a few hundred cycles, while lithium-ion batteries typically last for 1, 000.

让蓄电池制造商左右为难的是，充电的速度取决于电解质与电极之间接触的面积。

The battery-maker's dilemma is that the recharging rate depends on the area of contact between electrolyte and electrode.
