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.
This experimental design aims first to demonstrate a novel copper metal cavity electrode (Cu-MCE) for the convenient and fast investigation of powdery electro-active materials in general and silicon-based negative electrode materials for lithium-ion batteries in particular.
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
The incorporation of a high-energy negative electrode system comprising Li metal and silicon is particularly crucial. A strategy utilizing previously developed high-energy anode materials is advantageous for fabricating solid-state batteries with high energy densities.
Notably, superior dry mixing methods and advanced dry powder painting techniques (Ludwig et al., 2016; Zhou et al., 2020) need to be exploited to guarantee the mixing uniformity of electrode materials and afford a high bonding strength between powders and current collectors.
