Abstract
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.
