Abstract: A package structure of a soft package lithium battery is provided. Two joining sheets that are correspondingly joined are provided at positions at which peripheries of covering films are press-fit on each tab. Each of the joining sheets has a first press-fit area and a second press-fit area. Joining surfaces of the first press-fit areas of the two joining sheets are correspondingly joined to each other and fixedly sandwich the tab therebetween. The second press-fit area is folded downward away from the tab to the first press-fit area, and the second press-fit areas are press-fit and fixed to the covering films. The concave surface formed by folding between the first press-fit area and the second press-fit area of each of the joining sheets alleviates the problem that hot gases generated during battery discharging exerts an upward force to generate a gap at the press-fit position and lead to electrolyte leakage.

Abstract: The disclosure describes an exemplary binding layer formed on Aluminum (Al) substrate that binds the substrate with a coated material. Additionally, an extended form of the binding layer is described. By making a solution containing Al-transition metal elements-P—O, the solution can be used in slurry making (the slurry contains active materials) in certain embodiments. The slurry can be coated on Al substrate followed by heat treatment to form a novel electrode. Alternatively, in certain embodiments, the solution containing Al-transition metal elements-P—O can be mixed with active material powder, after heat treatment, to form new powder particles bound by the binder.

Abstract: A conductive connection structure for secondary batteries employs conductive portions disposed under two lateral sides of a cover plate to conductively connect to at least one battery cell. The conductive portions disposed under the two lateral sides of the cover plate are bendable, and the conductive portions are bent toward outer sides of the cover plate, so that the conductive portions are disposed horizontally; a connecting portion is extended upward respectively from an anode and a cathode terminals on two lateral sides of each of the battery cells, and the connecting portions and the conductive portions are electrically connected. By modifying the design of the connection structure of the battery cells and the two conductive portions under the cover plate, a time for soldering the battery cells and the conductive portions for conductive connection is reduced, the connection is tighter and more reliable and manpower cost is reduced.
