Data confidence 85 high

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

Abstract Existing cathode electrode materials used in commercially available lithium-ion batteries (LIBs) exhibit inadequate electrochemical performance at low temperatures, significantly constraining their utility in regions with cold climates. Promising in this context, the NASICON-structure Na 3 V 2 (PO 4 ) 3 (NVP) nanomaterial was successfully synthesized using a modified Pechini method and consequently evaluated in LIBs. Benefiting from the reduced particle size and mixed ions resulting from the replacement of Na with Li ions, the cathode exhibits an exceptionally high performance at both room and low temperatures, demonstrating at −20 °C the capacity of 83.05 mAh g −1 at 0.2 C, which is 84.33% of that at the room temperature. With such remarkable efficiency, NVP emerges as a compelling cathode candidate for low-temperature LIBs.
