  A modifier for polyvinylidene fluoride (PVDF), which improves the adhesion of PVDF to a metal, a binder resin composition for battery and a battery using the PVDF modifier are provided. The modifier for polyvinylidene fluoride herein is a modifier in which the peeling strength of a specific cured film to an aluminium foil is 20 g/cm or more, and the specific cured film is obtained from a mixture of 6 parts by mass of the modifier for polyvinylidene fluoride and 14 parts by mass of a polyvinylidene fluoride composition. The modifier preferably contains a macromonomer copolymer (X), obtained by polymerizing both a macromonomer (A) having unsaturated double bonds and a vinyl monomer (B) having polar groups. The macromonomer (A) is preferably a methacrylic acid ester-based macromonomer (A-1). The vinyl monomer (B) is preferably a methacrylate, and a fluoroalkyl methacrylate.

  In a lithium ion secondary battery according to one embodiment of the present invention, an electrode includes an electrode active material, a conductive auxiliary agent, and a binding material configured by a binding component that binds the conductive auxiliary agent and forms a conduction path between the electrode active material, and by a melting point depressant that lowers a melting point of the binding component. The melting point depressant is a PTC functionality-imparting component that lowers the melting start temperature of the binding material and imparts the PTC functionality to the lithium ion secondary battery. The lithium ion secondary battery according to the invention is configured such that, when short circuit heat generation has occurred within the battery due to a conductive foreign substance, the binding material at a periphery of the foreign substance melts to sever the conduction path.

  在根据本发明一个实施例的锂离子二次电池中，电极包括电极活性材料、导电辅助剂和结合材料，结合材料由结合导电辅助剂并在电极活性材料之间形成传导路径的结合成分和降低结合成分熔点的熔点抑制剂配置而成。熔点抑制剂是一种 PTC 功能赋予成分，可降低结合材料的熔点起始温度，并将 PTC 功能赋予锂离子二次电池。根据本发明，锂离子二次电池的构造是，当导电异物在电池内产生短路热量时，异物外围的结合材料熔化，切断传导路径。
