Counter electrode: Li; reference redox couple: Li<sup>+</sup>/Li; scan rate: 5 mV s<sup>−1</sup>. Electrolyte composition as in Figure <a href="../fig1/">1</a>. The activation of the process of NiO<sub><i>x</i></sub> oxidation is proven by the increase of the current density upon repetitive cycling. No further increase of the exchange current is observed after 70 cycles. Arrows indicate the verse of potential scan.</div>
