Abstract
Official abstract text for this publication.
Provided is a lithium secondary battery having a higher capacity and a longer life. The lithium secondary battery includes: a positive electrode including a material capable of intercalation and deintercalation of a lithium ion; a lithium ion-conductive electrolyte including a salen-based metal complex; and a negative electrode including a material capable of occlusion and release of a lithium metal or a lithium ion. The salen-based metal complex is selected from (R,R)-(−)-N,N′-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediaminotitanium chloride (TiSl), VSl, CrSl, MnSl, FeSl, CoSl, and RuSl.
