Predoping method for lithium, lithium-predoped electrode, and electricity storage device
A predoping method for lithium, which is characterized by mixing and kneading, in the presence of a solvent, lithium metal with (a) silicon and a composite dispersion of silicon and silicon dioxide, (b) particles represented by SiOx (wherein 0.5≦x<1.6) and having a fine structure wherein fine silicon particles are dispersed in a silicon-based compound, and (c) an Si-based material that is a mixture of one or more oxides selected from among the lower oxides of silicon represented by the above-mentioned formula and that is capable of absorbing and desorbing lithium ions; a lithium-predoped electrode which uses the predoping method for lithium; and an electricity storage device.
