A drying channel for a pole piece to pass through is formed in the oven apparatus; a heating plate assembly is arranged on each of two opposite sides of the drying channel correspondingly; and each heating plate assembly comprises a nano carbon heating plate that is, once powered, capable of generate heat. A pole piece that has undergone coating can pass through the drying channel, and is dried simultaneously from the upper and lower sides thereof by the heating plate assemblies on the two opposite sides of the drying channel, and is therefore heated relatively uniformly. Moreover, the heating plate assemblies use nano carbon heating plates to heat the pole piece, and after the nano carbon heating plates are powered and generate heat, the heat generated thereby is conducted by means of heat radiation, and can penetrate the surface of the pole piece with more ease, thereby more uniformly heating the inner layer and the outer layer of the pole piece. Thus, upon drying by the oven apparatus, the difference between the degree of dryness of the inner layer and the outer layer of the pole piece is small, and the pole piece is therefore less prone to cracking.
