New insights into the silicon-based electrode's irreversibility along cycle life through simple gravimetric method

▸ Simple gravimetric method gives broad overview of electrode's irreversibility. ▸ Mass and thickness increase due to continuous liquid electrolyte degradation. ▸ CMC grafting decreases reactivity between Silicon and liquid electrolyte. ▸ FEC and VC decrease reactivity between Silicon and liquid electrolyte. ▸ The binder has mechanical and chemical critical role for electrode stability.
