PURPOSE:To obtain a lithium secondary cell superior in operating voltage, discharge capacity and cycle life because of hard growth of dendrite even in the case of using a negative electrode comprising metallic lithium, and to obtain an electrolytic system superior in energy density and electromotive force. CONSTITUTION:An electrolytic system and a lithium secondary cell are arranged in such a way that an electrolytic system for a lithium secondary cell formed by including Si ion, Fe ion and/or An ion in solid electrolyte or non-aqueous solvent including lithium and/or lithium ion, and a negative electrode 3 comprising the electrotylic 4 and pure lithium, are in their state to be in mutual contact. |
