A lithium slurry battery system is provided. The system includes a lithium slurry battery and a maintenance and regeneration equipment for the battery. The battery includes: a case, a cell core accommodated in the case, and a cover butting device. The case is provided with a cover and a case body. The cover butting device is arranged on the cover and is provided with a first cover port and a second cover port. The maintenance and regeneration equipment includes: a gas storage tank for storing gas, a liquid storage tank for storing liquid; a gas recovery storage tank for storing gas recovered from the lithium slurry battery; a liquid recovery storage tank for storing liquid recovered from the lithium slurry battery; and an equipment butting device provided with a first equipment port and a second equipment port.

Lithium slurry battery system

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.

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

A lithium ion flow battery comprising cathode current collectors (), an anode current collector (), a cathode reaction chamber (), an anode reaction chamber (), a separator (), a cathode suspension solution () and an anode suspension solution (), wherein the cathode and anode current collectors are located at both sides of the separator respectively and are in close contact with the separator to form sandwich composite structure layers of the cathode current collector, the separator and the anode current collector; and in that several sandwich composite structure layers are arranged in sequence in an order that current collectors with the same polarity are oppositely arranged, and the electrode suspension solution continuously or intermittently flows in a battery reaction chamber between adjacent sandwich composite structure layers. Thus, the size of the battery reaction chamber can be flexibly designed according to the viscosity of the electrode suspension solution without increasing the polarization internal resistance of the battery, thereby solving the restriction conflict existing in the existing lithium ion flow battery between the size of the battery reaction chamber and the polarization internal resistance of the battery.
