Abstract
A main object of the present disclosure is to provide an anode slurry that gives an all solid state battery with suppressed fluctuation of restraining pressure. The present disclosure achieves the object by providing an anode slurry for an all solid state battery, the anode slurry including a Si-based anode active material, a first dispersion medium and a second dispersion medium; and the anode slurry satisfying: (i) when a hydrogen bond term σH of Hansen solubility parameter of, the Si-based anode active material, the first dispersion medium, and the second dispersion medium, are respectively regarded as σH, σHand σH, and when ΔσH=σH−σH, and ΔσH=σH−σH, the ratio ΔσH/ΔσH, which is a ratio of ΔσHwith respect to ΔσHis 0.96 or less; (ii) when Tdesignates a boiling point of the first dispersion medium, and Tdesignates a boiling point of the second dispersion medium, T−T≤3° C.; and (iii) when Wdesignates a content of the first dispersion medium and Wdesignates a content of the second dispersion medium, 0.1≤W/(W+W)≤0.25.
