Abstract

Abstract: Lithium–sulfur (Li–S) batteries are one of the most promising next‐generation batteries owing to their ultra‐high theoretical energy density and that sulfur is an abundant resource. During the past 20 years, various sulfur materials have been reported. As a molecular‐scale sulfur‐composite cathode, sulfurized pyrolyzed poly(acrylonitrile) (S@pPAN) exhibits several competitive advantages in terms of its electrochemical behavior. Although it was first reported in 2002 S@pPAN is currently attracting increasing attention. In this Minireview, we summarize its molecular model and explore the correlation between its structure and its exceptional electrochemical performance. We classify the modification strategies into three types, including material improvement, binder, and electrolyte screening. Several research and development directions are also suggested. Abstract : Sulfuriertes pyrolysiertes Poly(acrylnitril) (S@pPAN) zeigt überlegene Eigenschaften als Schwefel‐Kompositkathode. Das Material vermeidet die Auflösung von Polysulfiden und bietet einen alternativen Festkörperumwandlungsprozess. Dieser Kurzaufsatz stellt Konzepte zur Entwicklung besserer Batterien auf der Grundlage des vielversprechenden S@pPAN‐Komposits vor.
