  • Lithium-ion secondary battery and method of producing same
    Patent number: 10050270
    Abstract: A lithium-ion secondary battery including positive and negative electrodes, a separator element, an electrical conductor element and a binder, wherein the positive electrode includes 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 includes carbon black and a fibrous carbon material and wherein the negative-electrode material includes a graphite carbon material having at least one carbon phase selected from a graphene phase and an amorphous phase, and further includes carbon black and a fibrous carbon material, and wherein the binder includes a water-soluble synthetic resin or a water-dispersible synthetic resin. The most preferred positive electrode includes LiFePO4, The most preferred negative electrode includes artificial graphite or graphitazable powder. The most preferred binder is carboxyl methyl cellulose further including a surface active agent.
