Cycling behavior of thin film LiAl electrodes with liquid and solid electrolytes
The present study represents one aspect of a project which is concerned with the development of a rechargeable solid-state lithium battery for traction applications. The use of an electrode consisting of unalloyed lithium involves certain problems, which are related to a reaction with the electrolyte, dendrite formation, and shape change. Dey (1971) has found that lithium will alloy readily with aluminum. Electrochemical investigations of this binary combination in either molten salt or liquid organic electrolytes have been reported. The current study provides results of tests in which a LiAl electrode was kept in contact with solid polyethylene oxide (PEO). Other work conducted involved the use of the liquid propylene carbonate/LiClO4 (PC) as electrolyte for preparation of the LiAl alloy. On the basis of the obtained results, it is concluded that LiAl must be considered as a promising electrode material for solid-state rechargeable lithium cells. 21 references.
