摘要： An energy storage device can include a cathode, an anode, and a separator between the cathode and the anode, where the anode comprises a first lithium ion intercalating carbon component and a second lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, and the second lithium ion intercalating component can include graphite or soft carbon. A ratio of the hard carbon to the graphite or of the hard carbon to the soft carbon can be between 1:19 to 19:1. The anode may comprise a first lithium ion intercalating carbon component, a second lithium ion intercalating carbon component and a third lithium ion intercalating carbon component. The first lithium ion intercalating carbon component can include hard carbon, the second lithium ion intercalating carbon component can include soft carbon, and the third lithium ion intercalating carbon component can include graphite.

摘要： An energy storage device can have a first graphite film, a second graphite film and an electrode divider ring between the first graphite film and the second graphite film, forming a sealed enclosure. The energy storage device may be compatible with an aqueous electrolyte or a non-aqueous electrolyte. A method of forming an energy storage device can include providing an electrode divider ring, a first graphite film and a second graphite film. The method can include pressing a first edge of the electrode divider ring into a surface of the first graphite film, and pressing a second opposing edge of the electrode divider ring into a surface of the second graphite film to form a sealed enclosure. The sealed enclosure may have as opposing surfaces the surface of the first graphite film and the surface of the second graphite film.
