  • Publication number: 20200219669
    Abstract: There is provided a means capable of suppressing generation of a lithium dendrite at the time of charging and discharging while sufficiently suppressing an amount of gas generated at the time of initial charging of an electric device. When a lithium ion is doped in advance to a negative electrode active material, which is used in an electric device including a positive electrode and a negative electrode, after performing a pre-doping step of doping the lithium ion to a negative electrode active material to be doped to reduce a potential (vs. Li+/Li) of the negative electrode active material to be doped with respect to a lithium metal, a dedoping step of dedoping the lithium ion from the negative electrode active material doped with the lithium ion in the pre-doping step to increase a potential (vs. Li+/Li) of the negative electrode active material with respect to the lithium metal is performed.

  • Patent number: 8404126
    Abstract: A resist layer is formed over one surface of a current-collector material, while a resist layer having a predetermined pattern is formed on the other surface of the current-collector material. Through-holes are formed on the current-collector material through an etching process. An electrode slurry is applied onto the current-collector material formed with the through-holes without removing the resist layers. Specifically, since the through-holes are closed by the resist layer, the electrode slurry does not pass through the through-holes to leak out. Therefore, the current-collector material can be conveyed in the horizontal direction, whereby the productivity of an electrode can be enhanced. The resist layers are made of PVdF, and the resist layers are removed in a heating and drying step in which the PVdF is dissolved.
