Abstract

The invention discloses a slurry separation and recovery device. The device comprises a device frame body and at least two flow guide structures which are arranged at intervals along the length direction of the device frame body and are located at the top of the device frame body, wherein a first recovery cavity and a second recovery cavity which are spaced in the thickness direction of the deviceframe body are formed in the device frame body, the first recovery cavity upwards penetrates through the portion, located between the two flow guide structures, of the top of the device frame body toform a first material return opening, the second recovery cavity upwards penetrates through the top of the device frame body to form a second material return opening, and the flow guide structures extend to the second material return opening so that the slurry separation and recovery device can separate and recover residual coating tab film and slurry. In addition, the invention further disclosesa lithium battery coating recovery system.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a lithium battery coating recovery system and a slurry separation and recovery device thereof. Background technique [0002] Lithium-ion batteries have many advantages such as high energy density, high output power, long charge and discharge life, and wide operating temperature range, so they are widely used in various portable electronic devices. With the advancement of society, people have higher and higher requirements for portable electronic devices, so people have higher and higher requirements for the weight volume density and capacity volume density of lithium-ion batteries, so more and more lithium-ion batteries use aluminum Plastic casing. The battery packaged in aluminum and plastic needs to use tabs to connect the positive and negative electrodes inside the battery to the outside because the shell is non-conductive. Among them, the tabs are generally made ...
