摘要:
Disclosed is a partial plating process for forming a patterned plating layer on a surface of a resin substrate. The partial plating process of the present invention comprises the following steps: subjecting the surface of the resin substrate to oxidation treatment, causing a compound, which has a structure capable of coordination to a metal atom or metal ion, to adhere in a pattered form on the oxidation-treated surface to form an initiator pattern, forming a plating layer on the initiator pattern by electroless plating, and allowing the plating layer to grow to a desired thickness, as needed. This invention also relates to partially plated resin substrates obtained by the process, and to a process for manufacturing multilayered circuit boards by using the partial plating process.

Disclosed is a negative electrode active material for a lithium ion secondary battery, which is capable of further improving the charge/discharge cycle characteristics. Also disclosed is a lithium ion secondary battery which uses the negative electrode active material for a lithium ion secondary battery. The negative electrode active material for a lithium ion secondary battery is composed of composite particles each of which has a core/shell structure configured of a core part that is formed from a polymer and a shell part that is formed of a metal layer. The metal layer of the shell part is formed by metal plating. Preferably, the metal layer comprises at least a metal layer (a1) that is formed by electroless plating and a metal layer (a2) that is formed by electrolytic plating, in this order from the core part side.
