Dry solids of anionically modified cellulose nanofibers with good redispersion are provided by incorporating 5 to 300% by mass of a water-soluble polymer relative to the anionically modified cellulose nanofibers during the preparation of the dry solids of anionically modified cellulose nanofibers.

The present invention provides a binder for positive electrode of lithium ion battery which is excellent in workability at the time of producing a positive electrode, is excellent in charge and discharge characteristics such as cycle characteristics and rate characteristics, and enables to possible to produce a positive electrode having an extended cycle life, as well as the present invention provides a slurry for forming positive electrode mixture layer of lithium ion battery, a positive electrode for lithium ion battery, and a lithium ion battery, using the same. As a binder for binding a positive electrode active material, a conductive aid and a current collector at a positive electrode of a lithium ion battery, by using one containing a polysaccharide introduced with at least one ion exchange group selected from the group consisting of sulfate groups and alkali metal sulfate groups, it is possible to provide a lithium ion battery with excellent charge and discharge characteristics and an extended cycle life.
