Cell-core for lithium slurry battery, and lithium slurry battery module

A no-liquid cell for lithium slurry battery, comprising multiple positive electrode pieces and negative electrode pieces overlapping alternately, wherein

• the positive electrode piece comprises a positive electrode grid, electric-conductive cathode particles and a cathode surface current-collecting layer,
• the positive electrode grid is a rigid or flexible supporting body with one or more independent grid units, and the grid unit is a through-hole or a recess-like blind-hole;
• the electric-conductive cathode particles are filled in the grid unit of the positive electrode grid to form an electric-conductive cathode layer,
• the electric-conductive cathode layer contains a part or all of the electric-conductive cathode particles in accumulated state without adhesive bonding, and the accumulated state includes powders accumulation, pressed sheet or pressed block, and
• the electric-conductive cathode particles are compound or mixture of a cathode active material and a conductive agent,
• the cathode surface current-collecting layer is fixed to the surface of the positive electrode grid, and the fixing manner includes adhesive bonding, mechanical pressing, coating, hot pressing or welding,
• the negative electrode piece comprises a electric-conductive lithium-intercalatable anode layer, wherein
• the electric-conductive lithium-intercalatable anode layer 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, and the accumulated state includes powders accumulation, pressed sheet and pressed block,
• the electric-conductive lithium-intercalatable anode particles are compound or mixture of a lithium-intercalatable anode material and a conductive agent, and
• the peripheral edge of the positive electrode piece and/or the negative electrode piece is insulated and sealed.
