Formation of the solid electrolyte interphase (SEI) on hard carbon electrode significantly influences performance batteries, in terms cycle performance, calendar life, and power characteristics. In sodium-ion batteries (SIBs), energetically inferior SEI formation mechanism, compared with lithium-ion (LIBs), results a thin, thermally vulnerable, less passivating electrode. Notably, for SIBs have higher lowest unoccupied molecular orbital (LUMO) energy level Na-solvated ethylene carbonate upstream-shifted swing voltage range, LIBs, which reduces deposition from insufficient overpotential development. Additionally, larger ionic radius Na to that Li-ion leads lower binding ions anion component, increasing solubility electrolytes. Consequently, thermal stability more-pronounced self-discharge during high-temperature storage, LIBs.
