  • Predoping method for lithium, lithium-predoped electrode, and electricity storage device
    Patent number: 9548165
    Abstract: 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.

  • Method for lithium predoping, method for producing electrodes, and electric energy storage device using these methods
    Patent number: 9147876
    Abstract: A predoping technique considered as highly practicable is an electrochemical method in which predoping is performed by assembling a battery such that an active material (electrode) and lithium are brought into direct contact with each other or short-circuited therebetween via an electric circuit, and by filling an electrolytic solution in the battery. However, in this case, much time is required, and there are problems such as the handling and the thickness accuracy of an extremely thin lithium metal foil that is not greater than 30 ?m thick. By mixing a lithium-dopable material and lithium metal together in the presence of a solvent, such problems can be solved.
