A surface-enabled, metal ion-exchanging battery device comprising a cathode, an anode, a porous separator, and a metal ion-containing electrolyte, wherein the metal ion is selected from aluminum (Al), gallium (Ga), indium (In), tin (Sn), lead (P), or bismuth (Bi), and at least one of the electrodes contains therein a metal ion source prior to the first charge or discharge cycle of the device and at least the cathode comprises a functional material or nano-structured material having a metal ion-capturing functional group or metal ion-storing surface in direct contact with the electrolyte. This energy storage device has a power density significantly higher than that of a lithium-ion battery and an energy density dramatically higher than that of a supercapacitor.
A partially or fully surface-enabled, metal ion-exchanging battery device comprising (a) a positive electrode (cathode), (b) a negative electrode (anode), (c) a porous separator disposed between said cathode and said anode, and (d) an electrolyte in physical contact with said cathode and said anode, wherein said electrolyte contains a metal ion that is exchanged between said cathode and said anode during an operation of said battery device and said metal is selected from aluminum (Al), gallium (Ga), indium (In), tin (Sn), lead (P), or bismuth (Bi), wherein at least one of said cathode and said anode contains therein a source of said metal ion prior to a first charge or a first discharge cycle of the battery device and at least the cathode comprises a functional material having a surface-borne metal ion-capturing functional group or a nano-structured material having a metal ion-storing surface in direct contact with said electrolyte to reversibly capture or store said metal ion during charge-discharge operations of said battery, wherein the functional material consists of or contains nano graphene selected from a single-layer graphene sheet or a multi-layer graphene platelet.
A partially or fully surface-enabled, metal ion-exchanging battery device comprising (a) a positive electrode (cathode), (b) a negative electrode (anode), (c) a porous separator disposed between said cathode and said anode, and (d) an electrolyte in physical contact with said cathode and said anode, wherein said electrolyte contains a metal ion that is exchanged between said cathode and said anode during an operation of said battery device and said metal is selected from aluminum (Al), gallium (Ga), indium (In), tin (Sn), lead (P), bismuth (Bi), or a combination thereof wherein at least one of said cathode and said anode contains therein a source of said metal ion prior to a first charge or a first discharge cycle of the battery device and at least the cathode comprises a functional material having a surface-borne metal ion-capturing functional group or a nano-structured material having a metal ion-storing surface in direct contact with said electrolyte to reversibly capture or store said metal ion during charge-discharge operations of said battery, wherein said nano-structured material comprises a nano-structured or porous disordered carbon material selected from a soft carbon, hard carbon, polymeric carbon or carbonized resin, meso-phase carbon, coke, carbonized pitch, carbon black, activated carbon, partially graphitized carbon, and combinations thereof.
A partially or fully surface-enabled, metal ion-exchanging battery device comprising (a) a positive electrode (cathode), (b) a negative electrode (anode), (c) a porous separator disposed between said cathode and said anode, and (d) an electrolyte in physical contact with said cathode and said anode, wherein said electrolyte contains a metal ion that is exchanged between said cathode and said anode during an operation of said battery device and said metal is selected from aluminum (Al), gallium (Ga), indium (In), tin (Sn), lead (P), bismuth (Bi), or a combination thereof;
