Definitions

  • the operating principle of a micro-battery is based on the insertion and deactivation of an alkali metal ion or a proton in the positive electrode of the micro-battery, preferably a lithium Li + ion from '' a metallic lithium electrode.
  • the micro-battery is formed by a stack of layers obtained by CVD or PVD deposition, respectively constituting two current collectors, a positive electrode, an electrolyte, a negative electrode and, optionally, an encapsulation.
  • the elements of the micro-battery can be made of various materials:
  • this object is achieved by the fact that the first electrode is formed on a first metal strip by coating, then compression at cold, the first metal strip being removed before forming the current collectors.
  • FIG. 1 to 5 illustrate the successive stages of a particular embodiment of a manufacturing method according to the invention.
  • FIG. 6 illustrates an alternative embodiment of the first steps of the method according to the invention.
  • PVDF / HFP is prepared.
  • the membrane 5 is an electrically and ionically conductive insulating membrane after activation. It is formed by a phase inversion process, which makes it possible to obtain a membrane having a controlled microporosity. This process involves the following three steps:
  • the current collector 7, which is not electrically connected to the integrated circuit 8 by the connection balls 9, is connected to the integrated circuit by at least one wire 10, soldered to a end on the current collector 7 and, at the other end on the integrated circuit 8.
  • the manufacturing process described above thus uses, in part, technologies analogous to those which are conventionally used for the manufacture of mini-batteries (coating of the layers of the active stack constituted by the electrodes and the electrolytic membrane).
  • the withdrawal metallic strips makes it possible to reduce the thickness of this stack as much as possible, which is then supplemented by the deposition of current collectors by techniques, of the PVD type, conventional in microelectronics.
