A general electrode coating system for lithium/sodium ion batteries

Abstract

The invention discloses a general electrode coating system for lithium / sodium ion batteries, which comprises a support plate, a base plate, a brushing device and a linear movement mechanism, a base is arranged on the support plate, a slot is recessed on the side of the base plate, and a slot is provided on the slot There is a buffer device inside, and when the support plate is inserted into the slot, it has a compressive force on the buffer device; a pressing device is provided outside the slot, and the pressing device is used to limit the ejection of the support plate; the brushing device includes a The upper roller has a roller shaft inside the roller, which can rotate around the roller shaft; the two ends of the roller shaft extend to the outside of the roller and are fixedly connected with the lifting structure respectively; the linear movement mechanism includes a screw rod, which is arranged on the bottom plate Sliders are slidably arranged on the two sides of the screw rod, and the sliders can pull the brushing device to slide through the connecting member. The invention prevents the displacement of the support plate and the battery base during the coating process through the buffer device and the pressing device, thereby ensuring the stability of the coating process.

Description

technical field [0001] The invention belongs to the technical field of battery processing, and in particular relates to a general electrode coating system for lithium / sodium ion batteries. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, the development and search for new clean and sustainable energy sources has become a crucial issue; lithium-ion batteries have the characteristics of high electrochemical capacity, high energy density and good cycle performance, and are widely used in portable electronics. It is widely used in products and large-scale energy storage equipment, and it is also the most widely used mobile power supply on the market. [0003] Sodium and lithium are the same main group elements in the periodic table, they have similar physical and chemical properties, and because of the wide distribution and low price of sodium resources, the production cost of batteries can be reduced, so it is ...
