Claim 0:
1. A lithium secondary battery comprising:
a positive electrode comprising a material capable of intercalation and deintercalation of a lithium ion;
a lithium ion-conductive electrolyte comprising a salen-based metal complex, wherein the salen-based metal complex is selected from
(R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminotitanium chloride; (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminovanadium chloride; (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminochromium chloride; (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminomanganese chloride; (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminoiron chloride; (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminocobalt; or (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminoruthenium chloride; and
a negative electrode comprising a material capable of occlusion and release of a lithium metal or a lithium ion.
