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

This article presents the results of a study of the electrochemical properties of cathodes based on polycrystalline samples of Na3Fe2(PO4)3 obtained by solid-phase synthesis and hot pressing. Factors affecting the electrochemical properties of cathodes based on Na3Fe2(PO4)3 obtained by solid-phase synthesis, hot pressing, and sol-gel are established. The prospects of using Na3Fe2(PO4)3 as a cathode material in sodium-ion batteries and the expediency of further modification of this compound in order to improve its electrochemical properties are substantiated.
