Zusammenfassung:	To provide a process for limiting leakage currents.SOLUTION: A solid-state microbattery includes: a substrate (S); a lithium-cobalt-oxide layer (2) forming a cathode having first and second opposite surfaces (20, 21); a lithium-based solid-state electrolyte (4) formed on the first surface (20) of the cathode (2), where the second surface (21) of the cathode (2) is oriented towards the substrate (S); and an anode (5) formed on the solid-state electrolyte (4). It is noteworthy that the lithium-cobalt-oxide layer (2) possesses a grain size that increases from the first surface (20) to the second surface (21).SELECTED DRAWING: Figure 8 【課題】漏れ電流を制限する方法を提供すること。【解決手段】本発明は、固体マイクロ電池であって：－基板（Ｓ）と；－第１および第２の反対側の表面（２０、２１）を有するカソードを形成するリチウム－コバルト－酸化物層（２）と；－カソード（２）の第２の表面（２１）が基板（Ｓ）に向けて配置された、カソード（２）の第１の表面（２０）に形成されたリチウム系固体電解質（４）と；－固体電解質（４）上に形成されたアノード（５）と；を備え、リチウム－コバルト－酸化物層（２）が、第１の表面（２０）から第２の表面（２１）へと増加する粒度を持つことが注目に値する、固体マイクロ電池に関する。【選択図】図８
