非水电解质二次电池用结构体、非水电解质二次电池以及该结构体的制造方法

Structure for nonaqueous electrolyte secondary batteries, nonaqueous electrolyte secondary battery, and method for producing said structure

Abstract

本发明的目的在于提供一种无需通过不良溶剂等复杂工序即可制成的非水电解质二次电池用结构体,本发明的非水电解质二次电池用结构体具有正极、隔膜、以及负极,其中在所述正极与所述隔膜之间以及所述负极与所述隔膜之间中的至少一处,具有含有偏氟乙烯类聚合物粒子而形成的中间层,在构成所述中间层的原料100质量份中,偏氟乙烯类聚合物粒子为60~100质量份。
The purpose of the present invention is to provide a structure for nonaqueous electrolyte secondary batteries, which can be produced without requiring cumbersome steps such as a step wherein a structure is passed through a poor solvent. A structure for nonaqueous electrolyte secondary batteries according to the present invention comprises a positive electrode, a separator and a negative electrode, and is characterized in that: an intermediate layer, which is formed to contain vinylidene fluoride polymer particles, is provided between the positive electrode and the separator and/or between the negative electrode and the separator; and the vinylidene fluoride polymer particles are contained in an amount of 60-100 parts by mass per 100 parts by mass of the material that constitutes the intermediate layer.
