BINDER COMPOSITION FOR SECONDARY CELL NEGATIVE ELECTRODE, SLURRY COMPOSITION FOR SECONDARY CELL NEGATIVE ELECTRODE, NEGATIVE ELECTRODE FOR SECONDARY CELL, AND SECONDARY CELL

摘要

[Problem] To provide a binder composition with which the adhesiveness between a collector and an electrode active substance layer after charging and discharging is high, and it is possible to improve cycle properties under a high temperature and low-temperature output properties of a secondary cell in particular. [Solution] The binder composition of the invention is characterized by comprising a binder and a propargyl group-containing compound, and the content of the propargyl group-containing compound is between 0.1 and 20 parts by mass per 100 parts by mass of binder.
