Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Recently, considerable attention has been paid to the study of solid electrolytes in lithium-ion batteries. Ion conductive ceramic material NASICON-type Li1+xAlxTi2-x(PO4)3 (LATP) is a promising solid electrolyte for lithium-ion batteries due to its stability in air. Here we report the results of LATP synthesis using the solution method. It has been found that the ionic conductivity of LATP is largely influenced by the preparation method. Pure LATP was obtained with the grain size of 100-700 nm. Measured ionic conductivity of the prepared LATP was in order of 10-5 S cm-1 at room temperature. Its typical particle size is between 100 and 700 nm, and its relative density is 89.5 percent.
