The battery container is especially suitable for placing a flexible battery. The fixing element of the battery container is used to fix the battery sets as bending. In order to avoid the damage from the friction acting on the surfaces of the battery cells, the frictionless layers are disposed among the battery cells as well as between battery cell and the flexible pack. The reservation region is used for placing a fan-shaped end as the flexible pack and the battery set are bent. Hence, the structural integrity, the safety and the bending ability of the battery sets placing in the battery container disclosed can be greatly improved. ## Claims ### Claim 1 A battery container, comprising, a flexible pack, comprising an accommodation region and at least one reservation region, the reservation region substantially connected to the accommodation region; and a battery set, disposed in the accommodation region and comprising: a plurality of battery cells, stacked and electrically connected to each other; at least one frictionless layer, disposed on at least one surface of the battery cell; and at least one fixing element, used to fix the battery cells; wherein the reservation region is used respectively for placing one fan-shaped end of the battery set due to different deformations of each of the battery cells as the flexible pack and the battery set are bent. ### Claim 2 (depends on 1) The battery container as claimed in claim 1, wherein flexible pack further comprises a terminal electrically connected to the battery set. ### Claim 3 (depends on 2) The battery container as claimed in claim 2, further comprising an electrical element disposed in the accommodation region and electrically connected to the terminal and the battery set. ### Claim 4 (depends on 1) The battery container as claimed in claim 1, wherein the fixing element is further electrically conductive. ### Claim 5 (depends on 2) The battery container as claimed in claim 2, further comprising an electrical element disposed in the accommodation region and electrically connected to the fixing element and the terminal or to the fixing element and the battery set. ### Claim 6 (depends on 1) The battery container as claimed in claim 1, wherein the frictionless layer is disposed on the surface between the two adjacent battery cells. ### Claim 7 (depends on 1) The battery container as claimed in claim 1, wherein the friction layer is disposed on the surface between the battery cell and the flexible pack. ### Claim 8 (depends on 1) The battery container as claimed in claim 1, wherein material of the flexible pack is selected from the group consisting of textile, leather, polymer material, metal and a combination thereof. ### Claim 9 (depends on 1) The battery container as claimed in claim 1, wherein the fixing element is selected from a rivet and/or a clamp. ### Claim 10 (depends on 1) The battery container as claimed in claim 1, wherein material of the frictionless layer is selected from the group consisting of polytetrafluoroethylene, polymer elastic material and a combination thereof. ### Claim 11 (depends on 10) The battery container as claimed in claim 10, wherein the polymer elastic material is selected form the group consisting of polystyrene-based material, polyurethane-based material, polyolefin-based material, dinens-based material, thermal plastic rubber, thermal plastic silicon-sulfide rubber, vinyl chloride-based material, polyester-based material, polyamide-based material, organic fluorine-based material, silicone and a combination thereof. ### Claim 12 (depends on 1) The battery container as claimed in claim 1, wherein the reservation region is a vacuum. ### Claim 13 (depends on 1) The battery container as claimed in claim 1, wherein the reservation is filled with a fluid and/or a plastic material. ### Claim 14 (depends on 1) The battery container as claimed in claim 1, further comprising at least one supporting element disposed in the reservation region. ### Claim 15 (depends on 14) The battery container as claimed in claim 14, wherein the supporting element has at least one inclined plane for guiding the battery set into the reservation region as the battery set is bent. ### Claim 16 (depends on 1) The battery container as claimed in claim 1, wherein length ratio of the battery set and the reservation region is not more than 200. ### Claim 17 (depends on 1) The battery container as claimed in claim 1, wherein the battery sets are electrically connected in parallel and/or in series. ### Claim 18 (depends on 1) The battery container as claimed in claim 1, wherein the flexible pack is an integrated body. ### Claim 19 (depends on 4) The battery container as claimed in claim 4, further comprising an electrical element disposed in the accommodation region and electrically connected to the fixing element and the terminal or to the fixing element and the battery set.
