Binder particle aggregates for electrochemical device electrodes, slurry compositions for electrochemical device electrodes, methods for their preparation, and electrodes and electrochemical devices for electrochemical devices

摘要

It is an object of the present invention to provide a new technique for securing coating properties of a slurry composition and exhibiting excellent high-voltage cycle characteristics in an electrochemical device. The binder particle aggregate for electrochemical device electrode of the present invention comprises a plurality of binder particles containing a polymer containing 75.0 mol% to 99.5 mol% of a nitrile group-containing monomer unit, and the pore content of the plurality of binder particles is 60% or more.
