The invention provides lithium battery baking and drying equipment. The lithium battery baking and drying equipment comprises solar conversion equipment, an oven and a transportation line; the solar conversion equipment is electrically connected with a controller, a temperature detector and a heating plate; the oven is provided with a first through hole; the temperature detector and the heating plate are arranged in the oven by penetrating through the first through hole; a second through hole is formed in the oven; the transportation line penetrates through the second through hole to enter theoven; a third through hole is formed in the oven; the transportation line penetrates through the third through hole, and penetrates out from the oven; and a groove is formed in the transportation line. The lithium battery baking and drying equipment uses a mode of heating assisted by solar temperature control, and achieves high drying efficiency, low power consumption, low outer surface temperature rise of the oven and uniform heating; and the perennial power consumption of each production line is lower compared with a traditional mode.
