Abstract The production of Li 2 CO 3 /C through reduction reaction in nonaqueous systems is a complex four‐electron, multi‐step process, and the short existence time intermediate monomers not conducive to observation, which causes great difficulties clarifying regulating path. Herein, ferrocene (Fc) as functional additive into electrolyte can stabilize discharge intermediates favor occurrence two‐electron path during RR, leads more stable operation Li‐CO battery; with assistance Fc, pathway battery also clarified. Theoretical calculation analysis combined experimental characterization observation confirms that Fc shorten distance interaction affecting solvent environment around + , products clarify depth are key factors pathway. C O 4 formed by 2‐electron favorable for reversible than 4‐electron This work provides inspiration mechanism improve electrochemical performance future.
