Abstract
To provide a positive electrode for a lithium ion battery having high energy density and being capable of rapid discharging. A positive electrode for a lithium ion battery, the positive electrode including a positive electrode current collector, a positive electrode active material layer formed on the surface of the positive electrode current collector, and a non-aqueous liquid electrolyte including an electrolyte containing lithium ions and a non-aqueous solvent, in which the positive electrode active material layer includes a positive electrode active material and voids, the voids are filled with the non-aqueous liquid electrolyte, and a proportion of the battery capacity based on a total amount of lithium ions in the non-aqueous liquid electrolyte existing in the positive electrode active material layer with respect to the battery capacity based on a total amount of the positive electrode active material is 3.5 to 15%.
