SECONDARY BATTERY ELECTRODE INK, LITHIUM-ION BATTERY, AND ELECTRONIC DEVICE

摘要

A secondary battery electrode ink is adapted to be discharged from a droplet discharge device to make an electrode layer of a secondary battery. The secondary battery electrode ink includes an active substance including at least one of a positive electrode active substance and a negative electrode active substance, and a liquid medium. The liquid medium dissolves and/or disperses the active substance. The liquid medium has a characteristic in which, when a cured epoxy adhesive material is put into the liquid medium under a sealed condition at an atmospheric pressure and a temperature of approximately 50° C. and left for ten days, a weight increase rate of the cured epoxy adhesive material is 130% or less.
