Beschreibung
Zusammenfassung:	Provided are a rechargeable electrochemical device which can be used to prepare a battery having a very high energy density, and its preparation method. The method comprises the steps of inserting a negative electrode(3) comprising indium as a main component, a uncharged positive electrode(3) having an active compound containing lithium and an electrolyte into a housing(1); and forming a lithium/indium negative electrode by additional formation of a device, to prepare a rechargeable electrochemical device which has a lithium-inserted positive electrode and a lithium/indium alloy negative electrode in a housing. Preferably the negative electrode contains at least 70 % of indium. Preferably the positive electrode contains M, and M is Ni, Co or Mn, and a compound containing M is LiMOx. Preferably the compound LiMOx is doped with at least one selected from Al, Ti, Mg, Zn and Cr.
