Preparing batteries with high energy and power densities, elevated cycleability and improved safety could be achieved by controlling the microstructure of the electrode materials and the interaction they have with the electrolyte over the working potential window.
Promising Si negative electrode material has been recently prepared by a DC discharge between a Si bar and a Pt wire through a solution (electrolyte) . A study of different electrolytes and different voltages was carried and, in most cases, spherical particles were obtained, as shown in figure 17.
Such improvement in the cycleability of the electrode is attributed to a variation in morphology that led to the formation of a protective layer, analogous to conventional carbon or metal oxide coatings.
The satisfactory achievements obtained from dry electrode processing stimulate this technique to be more competitive in developing advanced electrodes (Ludwig et al., 2017). Further exploring advanced dry coating methods toward large-scale electrode production is imperative considering their economic and environmental superiority.
