An aspect of the present invention relates to a negative electrode for a sodium molten salt battery, the negative electrode including a negative electrode current collector and a negative electrode mixture layer arranged on a surface of the negative electrode current collector, the negative electrode mixture layer including negative electrode active material particles and a film arranged on a surface of each of the negative electrode active material particles, the negative electrode active material particles containing hard carbon, and the film containing a sodium-containing sulfide.
First claim
Opening claim text (preview).
The invention claimed is: 1. A negative electrode for a sodium molten salt battery, comprising: a negative electrode current collector and a negative electrode mixture layer arranged on a surface of the negative electrode current collector, the negative electrode mixture layer including negative electrode active material particles and a film arranged on a surface of each of the negative electrode active material particles, the negative electrode active material particles containing hard carbon, and the film containing sodium sulfide. 2. The negative electrode for a sodium molten salt battery according to claim 1 , wherein the film has an average thickness of 10 to 500 nm. 3. The negative electrode for a sodium molten salt battery according to claim 1 , wherein the hard carbon contains sulfur, and the negative electrode mixture layer has a sulfur content of 0.05% by mass or more. 4. The negative electrode for a sodium molten salt battery according to claim 3 , wherein the hard carbon contains a mercapto group. 5. A sodium molten salt battery comprising: a positive electrode, the negative electrode according to claim 1 , a separator arranged between the positive electrode and the negative electrode, and a molten salt electrolyte having sodium ion conductivity.
