Title:
ELECTRODE MIX, METHOD FOR PRODUCING ELECTRODE MIX, AND METHOD FOR PRODUCING ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2020/054274
Kind Code:
A1
Abstract:
This electrode mix contains a vinylidene fluoride-based polymer, a dispersion stabilizer, an active material, and a dispersion medium. In the vinylidene fluoride-based polymer, the medium diameter determined by a laser diffraction scattering method is 500 μm or less, the maximum melting peak temperature Tm1 of the first heating in a differential scanning calorimetry measurement is 130°C or higher, and TC10, which is the temperature at which the complex viscosity is 10 times the complex viscosity at 30°C, is 40-80°C, the complex viscosity being measured at an angular frequency of 10 rad-1 while heating the electrode mix from 25°C to 80°C at a heating rate of 5°C/min using a parallel plate rheometer.
