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: Various embodiments of a novel chemical synthesis route for lithium ion battery applications 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.

Abstract: A power supply system using an energy storage cell includes at least one lithium cell module; a voltage balance device, received and built in the lithium cell module, for performing voltage balance; and a cell module voltage monitoring device, disposed between a load and the lithium cell module, for monitoring and controlling working voltage ranges of all the lithium cell modules. The voltage balance device built in each lithium cell module performs charging correction on a lithium cell unit in which a capacitance difference is caused by a fabrication process or caused subsequently, to prevent overcharge damage of the lithium cell unit caused by the capacitance difference. The cell module voltage monitoring device is provided on an external line, and only a correct total charge voltage needs to be provided to charge the lithium cell module.

Abstract: A sealing method for battery containers which employs a first fixture to engage with the outer peripheries of edges of an opening of a container made from metal sheets, in order to define a shape of the opening of the container; then a second fixture is inserted into an inner space of the container from its opening, so that the edges of the opening of the container are shaped due to the ductility and malleability properties of metal sheets, and lateral surfaces of the container are made flat; lastly, a cover is placed on the opening of the container to have the container sealed by a welding means. The sealing method can restore an original shape of the container from a deformed state by using the fixtures, so that an entire sealing process for battery containers can be executed by automation in order to save labor costs.
