In the no-liquid cell-core, the electric-conductive cathode particles without adhesive bonding and/or the electric-conductive lithium-intercalatable anode particles without adhesive bonding have an accumulation porosity of more than 5% and less than 60%. When immerging in electrolyte, the electric-conductive cathode particles without adhesive bonding and/or electric-conductive lithium-intercalatable anode particles without adhesive bonding can move in the electrolyte and independently form a positive electrode slurry and/or a negative electrode slurry. The electric-conductive cathode particles may account for from 10% to 90% of the mass of the positive electrode slurry, and preferably from 15% to 80%. The electric-conductive lithium-intercalatable anode particles may account for from 10% to 90% of the mass of the negative electrode slurry, and preferably from 15% to 80%. The electric-conductive cathode particles have a mean particle diameter of 0.05 to 500 μm, and the mass ratio of the cathode active material to the conductive agent is 20 to 98:80 to 2; and the electric-conductive lithium-intercalatable anode particles have a mean particle diameter of 0.05 to 500 μm, and the mass ratio of the lithium-intercalatable anode material to the conductive agent is 20 to 98:80 to 2.

The cathode active material may be selected from the group consisting of lithium iron phosphate, lithium manganese phosphate, lithium silicate, lithium iron silicate, sulfate compounds, sulfur carbon composite, sulfur, titanium sulfur compounds, molybdenum sulfur compounds, iron sulfur compounds, lithium-doped manganese oxide, lithium cobalt oxide, lithium titanium oxide, lithium vanadium oxide, lithium nickel manganese oxide, lithium nickel cobalt oxide, lithium nickel cobalt aluminum oxide, lithium nickel aluminum oxide, lithium nickel cobalt manganese oxide and lithium iron nickel manganese oxide, or a mixture thereof.
