Abstract Low‐concentration electrolytes (LCEs) present significant potential for actual applications because of their cost‐effectiveness, low viscosity, reduced side reactions, and wide‐temperature electrochemical stability. However, current electrolyte research predominantly focuses on regulation strategies conventional 1 m electrolytes, high‐concentration localized leaving design principles, optimization methods, prospects LCEs inadequately summarized. face unique challenges that cannot be addressed by the existing theories approaches applicable to three common mentioned above; thus, tailored provide development guidance are urgently needed. Herein, a systematic overview recent progress in is provided subsequent directions suggested. This review proposes core challenge high solvent ratio LCEs, which triggers unstable organic‐enriched electrolyte/electrode interface formation anion depletion near anode. On basis these issues, modification including passivation construction solvent‒anion interaction optimization, used various rechargeable battery systems. Finally, role advanced simulations cutting‐edge characterization techniques revealing LCE failure mechanisms further highlighted, offering new perspectives future practical application next‐generation batteries.
