<P>PROBLEM TO BE SOLVED: To provide ink for a secondary battery electrode giving little damage to a droplet discharging head used in a droplet discharging method, especially, to an epoxy system adhesive to be a resin part, and therefore, excellent in discharge stability and capable of restraining shortening of life of the droplet discharge head, as well as a lithium-ion battery and an electronic equipment obtained by using the same. <P>SOLUTION: The ink for a secondary battery electrode is used in manufacturing an electrode layer including an active material in a droplet discharge method, and comprises a cathode active material or an anode active material and a fluid medium dissolving and/or dispersing the active material. The fluid medium has a weight increasing rate of 130% or less of a hardened matter of an epoxy system adhesive, after the epoxy system adhesive is kept standing for ten days under atmospheric pressure and at an environment of 50°C in the sealed fluid medium. <P>COPYRIGHT: (C)2009,JPO&INPIT |
