    摘要: The preparation of a slurry so as to exhibit no strong alkalinity not only needs a strict pH control, but also needs once dispersing a positive electrode material in water and the operation of drying after the treatment, and other operations, thereby leading to the complication of the operations and a decrease in the yield. In consideration of the above-mentioned problems, the present invention provides a method for producing a positive electrode plate for a lithium ion rechargeable battery, which exhibits less complication of the operations and less decrease in the yield and can prevent the gelation of a positive electrode material slurry. The above-mentioned problems can be solved by a positive electrode for a lithium ion rechargeable battery containing a positive electrode active material capable of absorbing/desorbing lithium ions, a nitrile group-containing polymer, and a binder.
