The present invention discloses a new metal cyano-substituted benzimidazolide salt having formula (I) and its preparation. This new cyano-substituted benzimidazole derivatives exhibited excellent thermal stability. The organic salt of the present invention were soluble in an alkyl carbonate solvent, such as propylene carbonate (PC), dimethyl carbonate (DMC) and ethylene carbonate (EC)/DMC cosolvent. The non-aqueous electrolyte prepared by mixing the organic metal salt of the present invention with the alkyl carbonate solvent shows high conductivity and excellent electrochemical stability. The non-aqueous electrolyte is suitable for use in primary or secondary rechargeable batteries.
