Abstract: This lithium electrochemical device includes a stack of layers suitable for constituting a micro-battery deposited on a substrate and encapsulated using a protective cap sealed onto the substrate. It includes two collectors of the current generated by the micro-battery and at least one insulating layer inert as regards lithium. The collectors and the insulating layer or layers are deposited on the substrate. The protective cap is sealed onto the substrate using the layers constituting the current collectors and the insulating layer or layers. The cap has layers of the same nature, positioned in the same order in line with their respective layers deposited on the substrate, so that when the cap is sealed onto the substrate, the respective layers deposited on the cap and on the substrate come into contact with each other to provide the actual seal of the cap on the substrate.

Abstract: The lithium-ion microbattery comprises a positive electrode having a first Li+ ion storage capacity and a first thickness made from a first lithium insertion material, an electrolyte and a negative electrode having a second storage capacity and a second thickness made from a second insertion material. The thicknesses are such that the ratio of the first storage capacity over the second storage capacity is greater than or equal to 10 and lower than or equal to 1000. During the first charging of the micro-battery, the Li+ ions are inserted in the negative electrode and completely saturate the second insertion material. When initial charging is continued, they form a metallic lithium layer between the electrolyte and the lithium-saturated negative electrode by electroplating. During the subsequent charging and discharging cycles, only the metallic lithium layer participates in transfer of lithium ions.
