  • Patent number: 10868337
    Abstract: 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.

  • Publication number: 20150093606
    Abstract: A Pump-free lithium ion liquid flow battery, battery reactor and preparation method of electrode suspension solution. The Pump-free lithium ion liquid flow battery includes a positive electrode liquid preparation tank (27), a negative electrode liquid preparation tank (32), a positive electrode liquid collection tank (30), a negative electrode liquid collection tank (35), a positive electrode conveying tank (31), a negative electrode conveying tank (36) and several battery sub-systems. The positive electrode conveying tank (31) intermittently moves vertically to and fro for the transportation of positive electrode suspension solution between the positive electrode liquid collection tank (30) and the positive electrode liquid preparation tank (27). The negative electrode conveying tank (36) intermittently moves vertically to and fro for the transportation of negative electrode suspension solution between the negative electrode liquid collection tank (35) and the negative electrode liquid preparation tank (32).
