[0234] 6.2. Examples 2-7, Comparative Examples 1-3
[0235] In "6.1.1. Preparation of Binder" of Example 1 above, except that the monomer composition and emulsifier amount were appropriately changed, the same procedure as Example 1 was carried out to prepare a composition containing the composition shown in Table 1. In the aqueous dispersion of the binder, water is removed under reduced pressure according to the solid content concentration of the aqueous dispersion or water is added to obtain an aqueous dispersion having a solid content concentration of 40%.
[0236] Next, in "6.1.2. Preparation of composition for electrical storage device" of Example 1 above, except that the anti-blocking agent has the type and the amount of addition described in Table 1, it is the same as Example 1 above. It was carried out to prepare compositions S2 to S7 and S11 to S13 for electrical storage devices.
[0237] In addition, it is the same as "6.1.3. Preparation of slurry for electrical storage dev...

[0239] Into a separable flask with a capacity of 7 liters, 150 parts by mass of water and 0.2 parts by mass of sodium dodecylbenzene sulfonate were charged, and the inside of the separable flask was sufficiently replaced with nitrogen. On the other hand, an ether sulfate type emulsifier (trade name "Adekaria SoapSR1025", manufactured by ADEKA Co., Ltd.) as an emulsifier (trade name "Adekaria SoapSR1025", manufactured by ADEKA Co., Ltd.), and as an emulsifier, 60 parts by mass of water and 0.8 parts by mass in terms of solid content were added to another container Monomer 2,2,2-trifluoroethyl methacrylate (TFEMA) 20 parts by mass, acrylonitrile (AN) 10 parts by mass, methyl methacrylate (MMA) 25 parts by mass, 2-ethylhexyl acrylate 40 parts by mass of ester (EHA) and 5 parts by mass of acrylic acid (AA) were sufficiently stirred to prepare a monomer emulsion containing a mixture of the aforementioned monomers. Thereafter, the temperature rise of the inside of the separable flask...

[0284] 6.7.1. Preparation of slurry for protective film formation
[0285] In 100 parts by mass of water, 20 parts by mass of titanium oxide (product name "KR380", manufactured by Titanium Industry Co., Ltd., rutile type, average particle diameter: 0.38μm) as inorganic particles are mixed with 5 parts by mass in terms of solid content relative to inorganic particles The electrical storage device composition S1 obtained in "6.1.2. Preparation of the electrical storage device composition" of the above-mentioned Example 1 and 1 part by mass of a thickener (manufactured by DAICEL Co., Ltd., trade name "CMC1120") TKFILMICS (R) 56-50 type (manufactured by PRIMIX Co., Ltd.) was used for mixing and dispersion treatment to prepare a protective film forming slurry in which titanium oxide was dispersed.
[0286] 6.7.2. Production of positive electrode
[0287] As the positive electrode, the surface of the active material layer of the positive electrode prepared in "6.5.5. Manufacturing and Eva...
