Definitions
- the invention relates to a microbattery comprising, in the form of thin layers, at least first and second electrodes between which a solid electrolyte is disposed.
- the invention also relates to a method of manufacturing such a microbattery.
- microbatteries some are based on the principle of insertion and disinsertion of an alkali metal ion such as Li + in the positive electrode.
- the electrochemical behavior of such microbatteries strongly depends on the materials constituting the active elements of the microbattery, that is to say the positive and negative electrodes and the electrolyte placed between the two electrodes.
