Abstract
This positive electrode for nonaqueous electrolyte secondary batteries is provided with a collector and a mixture layer that is formed on the collector. The mixture layer comprises: a lithium transition metal oxide that contains more than 50% by mole of Ni relative to the total number of moles of metal elements other than Li; a carbon material; a polymer compound that is soluble in N-methyl-2-pyrrolidone, while having a ring structure in each repeating unit; and a polyoxyethylene amine compound.
