Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a small and inexpensive composite power battery module with an excellent high-rate discharging characteristic and high safety.SOLUTION: A composite power battery module is provided with a lithium iron battery pack and a lithium manganese battery pack. The lithium iron battery pack has at least one lithium iron battery 10 including a positive electrode and a negative electrode electrically and serially connected to each other. The lithium manganese battery pack has at least one lithium manganese battery 20 including a positive electrode and a negative electrode electrically and serially connected to each other. The lithium iron pack and the lithium manganese battery pack are electrically and parallelly connected to each other. The negative electrode of the lithium manganese battery 20 is made of lithium titanate. The negative electrode of the lithium manganese battery 20 is made of graphite. The graphite is natural graphite or artificial graphite. The positive electrode of the lithium iron battery 10 is made of lithium iron phosphate.
