cited By 6International audienceThe influence of the Si particle size (85 nm versus 230 nm) on the mechanical stability of composite Si/C/carboxymethyl cellulose (CMC) electrodes is evaluated from in-operando dilatometry and acoustic emission measurements. A lower, more progressive and more reversible expansion/contraction of the electrode is observed with the Si 230 nm powder, with a maximum expansion of ∼140% and a residual irreversible expansion of ∼25% measured during the first cycle compared to ∼350% and ∼90% for the Si 85 nm based electrode. Moreover, during the 2nd cycle, an abrupt and very large expansion/contraction (up to ∼400%) is observed for the Si 85 nm based electrode, which results in the irreversible cracking and exfoliatio...
