Abstract
An electrode slurry contains (A) a cellulose fiber, (B) a carboxymethyl-group-containing cellulose ether or a salt thereof, and a particulate material containing at least (C) an electrode active material, and the cellulose fiber (A) has an average fiber length of 1 to 750 μm. The amount of the carboxymethyl-group-containing cellulose ether or the salt thereof (B) is 0.1 to 3 parts by weight based on 100 parts by weight of the total amount of the cellulose fiber (A), the carboxymethyl-group-containing cellulose ether or the salt thereof (B), and the electrode active material (C), in terms of solid content. The present invention provides an electrode slurry that allows an improved surface smoothness (coating uniformity) of an electrode and an improved coating property, a process for producing the electrode slurry, an electrode, a process for producing the electrode, a non-aqueous secondary battery, and a lithium-ion secondary battery.
