Description

Technical Field

[0001] The utility model relates to the technical field of solid-state battery production, in particular to a positive electrode baking mechanism for solid-state battery production. Background Art

[0002] Solid-state battery is a kind of battery technology. Different from lithium-ion battery and lithium-ion polymer battery commonly used today, solid-state battery is a battery using solid electrode and solid electrolyte. In the process of solid-state battery production, its positive electrode needs to be baked. The positive electrode baking process of solid-state battery is one of the key steps in the battery manufacturing process, which directly affects the performance and safety of the battery. Double-cone rotary vacuum dryer is generally used for heating of solid-state battery production. Double-cone rotary vacuum dryer is a double-cone rotary tank. Under vacuum state, heat transfer oil / water / steam is introduced into the jacket for heating and temperature control. Heat is continuously transferred to the material through the inner wall. The material is in the process of absorbing heat, and the water vapor in the material is evaporated to achieve the effect of uniform drying. The water vapor is discharged through a vacuum pump. The tank is in a vacuum state, and the heating system and the jacket form a convection closed cycle heating and temperature control.

[0003] However, heating the positive electrode of the solid-state battery through a double-cone rotary vacuum dryer not only has a relatively complex overall structure, but is also only suitable for batch processing and production. When a small number of solid-state batteries need to be heated, it is relatively energy-consuming, and the positive electrode sheets cannot be effectively separated during the heating process, resulting in the positive electrode sheets being easily piled up, reducing the baking effect. To this end, we provide a solid-state battery production positive electrode baking mechanism to solve the above problems. Utility Model Content
