摘要
针对薄膜电极的制备,设计并搭建了螺杆挤出式3D打印装置。首先设计了螺杆挤出装置,并对螺杆转速、喷头移速以及挤出流量进行了研究,搭建了一种基于电气比例阀的气路控制系统,可实现远程调控气压,从而为螺杆挤出装置供料。然后选取陶泥悬浮液进行打印实验,研究了螺杆转速、喷头移速对打印成型的影响,确定了Fe_(2)O_(3)油墨最优配方,进行实验来验证了打印薄膜的平整性,并确定了较优的工艺参数;最后以钒酸锂(LiV_(3)O_(8))为主体的热电池正极油墨为打印材料来打印薄膜电极,并测试其放电性能,结果表明,打印的薄膜电极成型精准,致密性良好,放电性能优异。该打印装置适合电极油墨材料的打印。
A screw extrusion 3D printing device has been designed and built for the preparation of thin-film electrodes.Firstly,a screw extrusion device was designed,and the screw speed,nozzle movement speed,and extrusion flow rate were studied.A gas path control system based on an electrical proportional valve was built,which can remotely adjust the air pressure to feed the screw extrusion device.Then,a printing experiment was carried out with ceramic slurry,the effect of screw speed and nozzle movement speed on printing molding was studied,and the optimal formula of Fe_(2)O_(3)ink was determined.Experiments were conducted to verify the flatness of the printed film,and better process parameters were determined.Finally,the thin film electrode was printed using thermoelectric cell positive electrode ink based on LiV_(3)O_(8)as the printing material,and its discharge performance was tested.The results show that the printed thin film electrode has precise molding,good compactness,and excellent discharge capacity.This printing device is suitable for printing electrode ink materials.
