The crucial trick is that although both the electrodes and the electrolyte appear solid, they are actually finely structured at the nanometre scale (a nanometre is a billionth of a metre).
关键点是虽然电极和电解质显然是固态的,它们事实上却具有完美的纳米(一纳米即十亿分之一米)构造。

Some theories suggest that the quantum nature of space should manifest itself at the ‘Planck scale’: the minuscule 10-35 of a metre, where a millimetre is 10-3 m.
