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

(60% of its initial capacity) after 150 cycles across various C-rates. In a pouch-cell configuration, the cell retained 64% of its initial capacity over 60 cycles. These findings underscore the potential of spin-coating and composite quasi-solid electrolytes in enabling high-performance, safe, and compact Li-S battery technologies for next-generation energy storage applications.
