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: A lithium battery cell structure is provided. A first-electrode conduction portion and a second-electrode conduction portion that are exposed outward are respectively provided on two sides of a soft package lithium battery inside the metal housing. The first-electrode conduction portions are respectively electrically connected and fixed to a first-electrode conductive sheet, and the first-electrode conductive sheet is electrically connected and fixed to a housing conductive sheet that is connected to the metal housing. The second-electrode conduction portions are respectively electrically connected and fixed to a second-electrode conductive sheet, and an other end of the second-electrode conductive sheet is electrically connected and fixed to the second electrode end. By adjusting the design of electrical connection between extending portions and the soft package lithium battery and the housing, the lithium battery cell is enabled to have better electrical conductivity and a better heat dissipation effect, and the sealing procedure made simpler.

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: Disclosed herein are certain embodiments of a novel chemical synthesis route for lithium ion battery applications. Accordingly, various embodiments are focused on the synthesis of a new active material using NMC (Lithium Nickel Manganese Cobalt Oxide) as the precursor for a phosphate material having a layered crystal structure. Partial phosphate generation in the layer structured material stabilizes the material while maintaining the large capacity nature of the layer structured material.
