| 摘要 |
The present invention provides a positive electrode (30) for lithium secondary batteries, including: a barrier layer, having a conductive material and at least one type of water-insoluble polymer that is soluble in organic solvents but insoluble in water, as a binder; and a positive electrode active material layer, being a positive electrode active material layer (35) stacked on the barrier layer, and having a positive electrode active material and at least one type of aqueous polymer that is insoluble in organic solvents but soluble or dispersible in water, as a binder. A content of the water-insoluble polymer in the barrier layer is 55 to 85 mass % with respect to 100 mass % of a total amount of the conductive material plus the water-insoluble polymer. |
