Abstract

Described is a positive electrode including a current collector, a first positive electrode active material layer on the current collector, and a second positive electrode active material layer on the first positive electrode active material layer. The first positive electrode active material layer includes a first positive electrode active material including a lithium iron phosphate-based compound. The second positive electrode active material layer includes a second positive electrode active material including a lithium iron phosphate-based compound and an oxide-based solid electrolyte. The oxide-based solid electrolyte is included in an amount in a range of about 0.1 wt% to about 3.0 wt% based on 100 wt% of a total of the second positive electrode active material layer.
