Densification of a NASICON-Type LATP Electrolyte Sheet by a Cold-Sintering Process

A NASICON-type Li(1.3)Al(0.3)Ti(1.7)(PO(4))(3) (LATP) electrolyte sheet for all-solid-state batteries was fabricated by a cold sintering process (CSP). The microstructure of the LATP sheet was controlled to improve the wettability which is an essential factor in CSP. The porous sheets of LATP were p...

description A NASICON-type Li(1.3)Al(0.3)Ti(1.7)(PO(4))(3) (LATP) electrolyte sheet for all-solid-state batteries was fabricated by a cold sintering process (CSP). The microstructure of the LATP sheet was controlled to improve the wettability which is an essential factor in CSP. The porous sheets of LATP were prepared by calcination the green sheets to remove the organic components and form the porous structure. By the CSP using the porous sheets, the densification of grain boundary was observed and further densified with increasing reaction time. The total conductivity of the prepared LATP sheet was improved from 3.0 × 10(−6) S/cm to 3.0 × 10(−4) S/cm due to the formation of necks between the particles at the grain boundary.
