That can be used to drive a current through an external circuit.

通过外部电路就可以利用这一点来导通电流。

Connect the plates through an external circuit and, as with a battery, a current will then flow.

之后通过外部电路将两块导电板进行连接，就像电池一样，电流就会开始流动。

That, though, happens only when the ion flow is balanced by a flow of electrons through an external circuit between the electrodes.

然而，只有当离子流被通过电极之间外部回路的电子流平衡时，这种情况才会发生。

The electrons, meanwhile, travel towards the cathode along an external circuit, which, in the case of an EV, powers its motor.

与此同时， 电子沿着外部电路向阴极移动，在电动汽车的情况下， 外部电路为其电机提供动力。

The process then reverses, but with the electrons in the external circuit powering a device, such as an EV's electric motor.

然后该过程反转，但外部电路中的电子为设备（例如 EV 的电动机）供电。

When they reach the anode, these ions are united with electrons supplied by the external circuit and lithium atoms are thus re-formed.

当它们到达阳极时，这些离子与外部电路提供的电子结合，从而重新形成锂原子。

The electrons are sent towards the anode through an external circuit, and the ions likewise dispatched in that direction via an electrolyte inside the battery.

电子通过外部电路被送往阳极，离子同样通过电池内部的电解质被送往阳极。

A lithium-ion battery generates energy by moving lithium ions from one electrode to the other, drawing electrons, and thus electrical current, through an external circuit and powering our devices.

锂离子电池通过锂离子从一个电极移动到另一个电极产生能量，移动的电子，就产生电流，连接到外部电路就能为设备提供电能。
