Popis: Negative electrodes in Li-Al batteries typically generate a porous, machanically stable microstructure. But agglomeration, associated with nonuniform elimination of porosity, have been detected. Agglomeration is the result of excessive sintering of the negative electrode. Excessive agglomeration can lead to poor utilization of active materials and may result in nonuniform swelling stresses. This paper collects data on the sinterability and deformability of simulated negative electrode compositions, in order to help prevent or minimize agglomeration. Aluminum and beta-Li-Al were each blended with eutectic LiCl-KCl salt and then cold pressed to form compacts. Beta-Li-Al compacts were much more deformable than Al specimens. The different deformation is evidently related to the lack of sintering in beta-Li-Al.
