Abstract:
A negative electrode for a nonaqueous electrolytic rechargeable battery capable of storing and discharging lithium ions is manufactured in the steps of forming a lithium metal layer on a carrier substrate by a gas phase method, superimposing the surface of the lithium metal layer formed on the carrier substrate on a negative electrode active material layer formed on a collecting body, storing the lithium metal layer into the negative electrode active material layer in nonaqueous electrolyte, and removing the carrier substrate from the negative electrode active material layer.
