LITHIUM AIR SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a new lithium air secondary battery capable of exhibiting cycle characteristics, current density characteristics or the like which are more excellent than before.SOLUTION: A lithium air secondary battery includes: an air electrode containing carbon as a main component; a negative electrode including metallic lithium or a lithium containing substance; and an organic electrolyte in contact with the air electrode and the negative electrode. Since the voltage difference between charge and discharge is small and reduction in discharge capacity can be suppressed even if charge/discharge cycle is repeated by containing hemocyanin in an electrolyte, a more excellent performance than before can be achieved.SELECTED DRAWING: Figure 1
