Abstract: The invention relates to a method for providing an electrode foil for producing a lithium-ion rechargeable battery, in which a metal foil is provided with a coating of electrode material and in which the coating of electrode material is plasma treated. The coating of electrode material is plasma-treated by the coating being subjected to an atmospheric plasma jet. The invention also relates to a method for producing a lithium-ion rechargeable battery, in which a first electrode foil for the negative electrode and a second electrode foil for the positive electrode are provided, in which the first and second electrode foils are arranged one above the other with a separator layer in between to form a foil stack and in which the foil stack is impregnated with a liquid electrolyte. The first and/or the second electrode foil is/are provided by the aforementioned method.

Abstract: A system for alternately applying and relieving pressure of predetermined portions of a foot of a user. The system includes a plurality of inflatable chambers, located at predetermined locations, corresponding to the predetermined portions of the foot and a pump. The system also includes a center pneumatic valve, coupled with the pump and with the inflatable chambers, for receiving air from the pump and inflating at least one of the inflatable chambers. The system further includes a pneumatic valve assembly, coupled with the center pneumatic valve. The pneumatic valve assembly is coupled with at least a respective one of the inflatable chambers. The pneumatic valve assembly is moveable between two positions, and changes position when a predetermined pressure value is achieved in the corresponding inflatable chamber. When the pneumatic valve assembly changes position, the center pneumatic valve changes position, thereby inflating another inflatable chamber.
