Provided is an anode particulate, having a dimension from 10 nm to 300 μm, for use in an alkali metal battery, the particulate comprising (i) an anode active material capable of reversibly absorbing/desorbing lithium or sodium ions, (ii) an electron-conducting material, and (iii) a lithium or sodium salt with an optional polymer or its monomer, but without a liquid solvent, for an electrolyte, wherein the electron-conducting material forms a 3D network of electron-conducting pathways in electronic contact with the anode active material and the lithium or sodium salt is in physical contact with the anode active material (so that the salt, when later impregnated with a liquid solvent, becomes an electrolyte forming a 3D network of lithium or sodium ion-conducting channels in ionic contact with the anode active material). The particulate can be of any shape, but preferably spherical or ellipsoidal in shape. Also provided is a cathode particulate.
An anode particulate having a dimension from 10 nm to 300 μm for use in an alkali metal battery, said particulate comprising (i) an anode active material capable of reversibly absorbing and desorbing lithium ions or sodium ions, (ii) an electron-conducting material, and (iii) a lithium salt or sodium salt with an optional polymer or its monomer, but without a liquid solvent, for an electrolyte, wherein said electron-conducting material forms a 3D network of electron-conducting pathways in electronic contact with said anode active material and said lithium salt or sodium salt, when forming into an electrolyte, forms a 3D network of lithium ion- or sodium ion-conducting channels in ionic contact with said anode active material and wherein said anode particulate has an electrical conductivity from about 10−6 S/cm to about 300 S/cm.
A cathode particulate for a lithium battery or sodium battery, wherein said cathode particulate is composed of (i) a cathode active material, (ii) an electron-conducting material, and (iii) a lithium salt or sodium salt with an optional polymer or its monomer, but without a liquid solvent, for an electrolyte, wherein the electron-conducting material forms a 3D network of electron-conducting pathways in electronic contact with the cathode active material and the lithium salt or sodium salt, when forming into said electrolyte, forms a 3D network of lithium ion- or sodium ion-conducting channels in ionic contact with the cathode active material, and wherein said cathode particulate has a dimension from 10 nm to 100 μm and an electrical conductivity from about 10−6 S/cm to about 300 S/cm.
