SECONDARY CELL USING AMORPHOUS VANADIUM OXIDE CONTAINING COPPER AS ANODE

摘要

PURPOSE: A secondary cell called the lithium battery is provided to improve life and stability at more than 500 times of charging/discharging cycles by comprising amorphous vanadium oxide containing copper component as the anode of the battery. CONSTITUTION: The battery comprises the anode consisting of amorphous vanadium oxide containing 0.1-15 wt.% of copper component having layered structure. The vanadium oxide compound may include at least one selected from a group consisting of iron, nickel, cobalt, tin, antimony, bismuth, magnesium, zinc and chrome in total amount of 0.1-15 wt.% based on the weight of compound. The vanadium oxide is used as a thin film state prepared by using PVD, CVD, sol-gel method, spin-coating method, electrostatic spray deposition manner and so on. The anode is produced by generating copper, tin, iron or antimony by means of sputtering gun and depositing it simultaneously with the vanadium oxide to form the amorphous structure.
