    摘要: A spacer-modified nano graphene platelet electrode, comprising: (a) multiple nano graphene platelets or sheets having an average thickness smaller than 10 nm; and (b) discrete, non-metallic nano-scaled particles that are disposed between two graphene platelets or sheets to serve as a spacer. In such a spacer-modified graphene electrode, large amounts of electrolyte-accessible pores are formed, enabling the formation of large amounts of electric double layer charges in a supercapacitor, which exhibits an exceptionally high specific capacitance.

    摘要: An inorganic material based surface-mediated cell (SMC) comprising (a) a cathode comprising a non-carbon-based inorganic cathode active material having a surface area to capture and store lithium thereon; (b) an anode comprising an anode current collector alone or both an anode current collector and an anode active material; (c) a porous separator; (d) a lithium-containing electrolyte in physical contact with the two electrodes, wherein the cathode has a specific surface area no less than 100 m2/g which is in direct physical contact with said electrolyte to receive lithium ions therefrom or to provide lithium ions thereto; and (e) a lithium source. This inorganic SMC provides both high energy density and high power density not achievable by supercapacitors and lithium-ion cells.

    摘要: 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 (A) non-Li alkali metals; (B) alkaline-earth metals; (C) transition metals; (D) other metals such as aluminum (Al); or (E) a combination thereof; and wherein 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 said electrolyte, and wherein the operation of the battery device does not involve the introduction of oxygen from outside the device and does not involve the formation of a metal oxide, metal sulfide, metal selenide, metal telluride, metal hydroxide, or metal-halogen compound. 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.
