SLURRY FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, METHOD FOR MANUFACTURING SLURRY FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY CELL, AND NON-AQUEOUS ELECTROLYTE SECONDARY CELL
The purpose of the present disclosure is to provide a slurry for a non-aqueous electrolyte secondary cell capable of obtaining an electrode mixture layer showing excellent adhesion with a current collector. The slurry for a non-aqueous electrolyte secondary cell, which is one mode of the present disclosure, contains: an electrode mixture containing an electrode active material, lithium carbonate, and carboxymethylcellulose or a salt thereof; and water. The lithium carbonate content is in the range of 33 to 300 ppm with respect to the total mass of the electrode mixture.
1 . A slurry for an electrode of a non-aqueous electrolyte secondary battery, including:
an electrode mixture including an electrode active material, lithium carbonate, and carboxymethyl cellulose or a salt thereof; and water,
wherein a content of the lithium carbonate is within the range from 33 ppm to 300 ppm based on the total mass of the electrode mixture.
2 . A method for producing a slurry for an electrode of a non-aqueous electrolyte secondary battery, comprising mixing: an electrode mixture including an electrode active material, lithium carbonate, and carboxymethyl cellulose or a salt thereof; and water, to thereby produce the slurry for an electrode,
wherein a content of the lithium carbonate is within the range from 33 ppm to 300 ppm based on the total mass of the electrode mixture.
3 . An electrode for a non-aqueous electrolyte secondary battery, comprising: a current collector and an electrode mixture layer on the current collector,
the electrode mixture layer including an electrode active material, lithium carbonate, and carboxymethyl cellulose or a salt thereof,
wherein a content of the lithium carbonate is within the range from 33 ppm to 300 ppm based on the total mass of the electrode mixture layer.
4 . A non-aqueous electrolyte secondary battery including a positive electrode, a negative electrode, and a non-aqueous electrolyte, wherein at least one of the positive electrode and the negative electrode is the electrode for a non-aqueous electrolyte secondary battery according to claim 3 .
