摘　　要：NASICON型快离子导体Li_(1.7)Al_(0.3)Ti_(1.7)(PO_4)_3(LATP)具有高离子电导率、宽的电化学稳定窗口、良好的热稳定性以及抑制枝晶生长等优点,在固态电池领域具有广阔的应用前景,但由于其无法做到很薄,使得内阻较大,限制了LATP的广泛应用。与传统工艺相比,通过光固化3D打印成形技术可以制备出薄层结构且致密度和精度高的LATP电解质,从而改善其内阻较大的问题。因此,本文分别从LATP光固化陶瓷浆料的制备、素坯的烧结工艺等方面进行分析与探讨,并对光固化3D打印LATP电解质的未来发展趋势进行了展望。The NASICON-type fast ionic conductor Li_(1.7)Al_(0.3)Ti_(1.7)(PO_(4))_(3)(LATP),which has the advantages of high ionic conductivity,wide electrochemical stabilization window,good thermal stability,and inhibition of dendritic growth,has a promising future in the field of solid-state batteries,but its inability to be made very thin,which results in a large internal resistance,has limited the wide application of LATP.Compared with the traditional process,LATP electrolytes with a thin layer structure and high density and precision can be prepared by light-curing 3D printing and molding technology,which can improve the problem of its large internal resistance.Therefore,this paper analyzes and discusses the preparation of LATP light-curing ceramic slurry and the sintering process of billet,respectively,and looks forward to the future development trend of light-curing 3D printed LATP electrolytes.
