Thermal treatment effect on electrochemical properties of silicon alloy anodes with poly(ether imide) binder for lithium-ion batteries

Magnetic Force Dilatometry of Silicon-NMC622 Lithium-Ion Coin Cells: The Effects of Binder, Capacity Ratio, and Electrolyte Selection

“…[42][43][44] There are few reports on the expansion of these electrodes, but Mukhan et al have reported that silicon electrodes containing pyrolyzed poly ether imide (PEI) binder showed significantly less expansion in the first two cycles than electrodes with a conventional polyvinylidene difluoride (PVDF) binder, which was attributed to the superior binder-silicon bonding between silicon and PEI than with PVDF. 45 In addition, electrode reversibility was improved with the pyrolyzed PEI binder, compared to electrodes made with PVDF or sodium-carboxymethyl cellulose binders.…”
