Negatives for secondary Li-batteries: Li-alloys or metallic Li?
1987Metallic lithium anodes as well as Li-alloy anodes are currently used in commercial rechargeable organic electrolyte batteries. The disadvantage of Li-alloys is of course low energy density and power density compared to metallic lithium; for some applications this disadvantage may be overbalanced by better cycling and storage behaviour of the alloys.
