摘要： There is provided a lithium-ion secondary battery comprising positive and negative electrodes, a separator element, an electrical conductor element and a binder, wherein the positive electrode comprises a lithium-containing metal phosphate compound coated with a carbon material having at least one phase selected from a graphene phase and an amorphous phase, and further comprises carbon black and a fibrous carbon material and wherein the negative-electrode material comprises a graphite carbon material having at least one carbon phase selected from a graphene phase and an amorphous phase, and further comprises carbon black and a fibrous carbon material, and wherein the binder comprises a water-soluble synthetic resin or a water-dispersible synthetic resin. The most preferred positive electrode comprises LiFe PO
4 . The most preferred negative electrode comprises artificial graphite or graphitazable powder. The most preferred binder is carboxyl methyl cellulose further comprising a surface active agent. Also provided is a method of making the lithium-ion secondary battery of the present invention.
