摘要

Provided is a no-liquid cell-core for a lithium slurry battery. The no-liquid cell-core comprises multiple positive electrode pieces and negative electrode pieces overlapping alternately. The positive electrode piece comprises an electric-conductive cathode layer and a cathode surface current-collecting layer, wherein the electric-conductive cathode layer contains a part or all of the electric-conductive cathode particles in accumulated state without adhesive bonding, and the cathode surface current-collecting layer is set on the surface of the electric-conductive cathode layer and contacted with it tightly. The negative electrode piece comprises an electric-conductive lithium-intercalatable anode layer which is a lithium-containing metal body and/or a layer containing a part or all of electric-conductive lithium-intercalatable anode particles in accumulated state without adhesive bonding. The peripheral edges of the positive electrode piece and/or the negative electrode piece are insulated and sealed. A lithium slurry battery module containing the no-liquid cell-core is also provided.
