摘要： A battery electrode composition is provided that comprises a composite material comprising one or more nanocomposites. The nanocomposites may each comprise a planar substrate backbone having a curved geometrical structure, and an active material forming a continuous or substantially continuous film at least partially encasing the substrate backbone. To form an electrode from the electrode composition, a plurality of electrically-interconnected nanocomposites of this type may be aggregated into one or more three-dimensional agglomerations, such as substantially spherical or ellipsoidal granules.

摘要： A cell includes a first current collector and a second current collector. A tail end of the first current collector exceeds a tail end of the second current collector by at least half a circle in a winding direction. The tail end of the first current collector does not include an active material and is bonded on an outer peripheral surface of an outermost circle of the first current collector by a first adhesive, the first adhesive is a double-sided tape or a hot melt adhesive. The cell is bonded with another double-sided tape or another hot melt adhesive on a side opposite from the tail end of the first current collector.

摘要： A cell includes a first current collector and a second current collector. A tail end of the first current collector exceeds a tail end of the second current collector by at least half a circle in a winding direction. The inventor of the present application finds that after the length of the first current collector is increased, and the tail end of the first current collector exceeds the tail end of the second current collector by at least half a circle, the following situation may occur: the outermost circle of the cell is the first current collector, the secondary outer circle is the first current collector, and the next secondary outer circle is the second current collector, such that both the outermost circle and the secondary outer circle of the cell are the first current collector.

摘要： A battery includes a first current collector, a first electrode layer, and a first counter electrode layer. The first counter electrode layer is a counter electrode of the first electrode layer. The first current collector includes a first electroconductive portion, a second electroconductive portion, and a first insulating portion. The first electrode layer is disposed in contact with the first electroconductive portion. The first counter electrode layer is disposed in contact with the second electroconductive portion. The first insulating portion links the first electroconductive portion and the second electroconductive portion. The first current collector is folded at the first insulating portion, whereby the first electrode layer and the first counter electrode layer are positioned facing each other.
