Abstract:
A lithium ion secondary battery includes a positive electrode including a positive electrode active material layer containing lithium iron phosphate, a negative electrode including a negative electrode active material layer containing graphite, and an electrolyte including a lithium salt and a solvent including ethylene carbonate and diethyl carbonate between the positive electrode and the negative electrode. When the battery temperature of the lithium ion secondary battery or the temperature of an environment in which the lithium ion secondary battery is used is T and given temperatures are T1 and T2 (T1<T2), in the case where T<T1, constant current charge is performed until voltage reaches a given value and then constant voltage charge is performed; in the case where T1≤T<T2, only constant current charge is performed; and in the case where T2≤T, charge is not performed.

Claim (Index 19):
The battery charger according to  claim 11 , wherein the positive electrode active material layer covered with single-layer graphene and multilayer graphene including two to hundred layers.
