Lithium and sodium ion battery tunnel furnace oven

The utility model discloses a tunnel furnace oven for lithium and sodium ion batteries, and relates to the technical field of lithium and sodium ion battery production. The tunnel furnace oven for the lithium and sodium ion batteries comprises an oven body, a tunnel cavity is formed in the oven body, and heating devices are fixedly installed on the two sides of the interior of the tunnel cavity. By arranging the tunnel cavity, the heating device, the first roller conveyor and the like, after a battery is placed in the battery placing basket, the battery moves in the tunnel cavity while being heated and baked and moves until moisture is discharged, meanwhile, the moisture in the battery can be monitored in real time, the traditional baking mode before liquid injection of the lithium battery and the sodium battery is changed, and the production efficiency of the lithium battery and the sodium battery is improved. The baking efficiency is improved, the production cycle is shortened, the productivity is improved,
