Abstract:
Provided is a vinylidene fluoride copolymer particle which is capable of efficiently exhibiting high adhesion between an electrode and a separator. The vinylidene fluoride copolymer particle of the present invention comprises vinylidene fluoride; and
a compound having an oxygen atom-containing functional group; wherein a ratio of oxygen atom in a surface of the vinylidene fluoride copolymer particle is higher than a ratio of oxygen atom in the vinylidene fluoride copolymer particle other than the surface thereof.
a compound having an oxygen atom-containing functional group; wherein a ratio of oxygen atom in a surface of the vinylidene fluoride copolymer particle is higher than a ratio of oxygen atom in the vinylidene fluoride copolymer particle other than the surface thereof.
