Thin alkali metal film member and method of producing the same

   
   

A member having a lithium metal thin film is provided, which is extremely thin, uniform, and not degraded by air. The member includes a substrate and a thin lithium metal film formed on the substrate by a vapor deposition method. The thin film typically has a thickness of 0.1 .mu.m to 20 .mu.m. The substrate is typically made of a metal, an alloy, a metal oxide, or carbon. The substrate typically has a thickness of 1 .mu.m to 100 .mu.m. The member is used as an electrode member for a lithium cell.

Un membre ayant une couche mince en métal de lithium est fourni, qui est extrêmement mince, uniforme, et non dégradé par avion. Le membre inclut un substrat et un film mince en métal de lithium formés sur le substrat par une méthode de dépôt de vapeur. La couche mince a typiquement une épaisseur de 0.1 mu.m au mu.m 20. Le substrat est typiquement fait de métal, alliage, oxyde de métal, ou carbone. Le substrat a typiquement une épaisseur de 1 mu.m au mu.m 100. Le membre est employé en tant que membre d'électrode pour une cellule de lithium.
