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 novel chemical synthesis route for lithium ion battery applications focuses 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.

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.
