A method for forming a lithium-ion type battery, including the successive steps of: forming, in a substrate, a trench; successively and conformally depositing a stack including a cathode collector layer, a cathode layer, an electrolyte layer, and an anode layer, this stack having a thickness smaller than the depth of the trench; forming, over the structure, an anode collector layer filling the space remaining in the trench; and planarizing the structure to expose the upper surface of the cathode collector layer.

Method for forming a vertical thin-film lithium-ion battery

A method for encapsulating a thin-film lithium-ion type battery, including the steps of: forming, on a substrate, an active stack having as a lower layer a cathode collector layer extending over a surface area larger than the surface area of the other layers; forming, over the structure, a passivation layer including through openings at locations intended to receive anode collector and cathode collector contacts; forming first and second separate portions of an under-bump metallization, the first portions being located on the walls and the bottom of the openings, the second portions covering the passivation layer; and forming an encapsulation layer over the entire structure.

Method of direct encapsulation of a thin-film lithium-ion type battery on the substrate

A method for forming a lithium-ion type battery including the steps of forming, over an at least locally conductive substrate, an insulating layer having a through opening; successively and conformally depositing a stack comprising a cathode collector layer, a cathode layer, an electrolyte layer, and an anode layer, this stack having a thickness smaller than the thickness of the insulating layer; forming, over the structure, an anode collector layer filling the space remaining in the opening; and planarizing the structure to expose the upper surface of the insulating layer.

Method for forming a thin-film lithium-ion battery

A hydrogen-oxygen fuel cell including a main cell and an auxiliary cell sharing a common electrolyte and having at least one separate electrode, circuitry for measuring the humidity ratio of the electrolyte, and control and switching circuitry for operating the main and auxiliary cells in parallel on a same load or separately on two different loads.

Humidity regulation fuel cell

A method for forming an integrated lithium-ion type battery, including the successive steps of: forming, on a substrate, a stack of a cathode layer made of a material capable of receiving lithium ions, an electrolyte layer, and an anode layer of the battery; forming a short-circuit between the anode and cathode layers; performing a thermal evaporation of lithium; and opening the short-circuit between the anode and cathode layers.
