An energy storage device includes an electrode assembly having a negative electrode plate and a separator wound around a tubular core material. The core material has a first line part and a second line part extending along a first imaginary line and a second imaginary line parallel to a long side surface of a case, respectively. At least one of the first line part and the second line part has a curved portion that protrudes toward the other beyond the first imaginary line or the second imaginary line. An inner peripheral edge of the negative electrode plate is located at a position other than the curved portion in at least one of the first line part and the second line part.

The invention relates to an energy storage system, the use of an energy storage system, a charging device, a system and a method for charging an energy store, the system comprising a re-chargeable energy store (1) and said energy store (1) having a rotatably mounted first roll (2) and a film (4) having electrodes (60, 61, 63, 65, 66).
