The Si negative electrode is a negative electrode material that stores Li through insertion of Li into Si. The following SEM image was obtained as a result of observing how Li was inserted by charging single-crystal Si with 40% charged while using the single-crystal Si as the negative electrode.
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
The origins of such a poor cycling performance are diverse. Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge.
