Batteries based on sulfur cathodes offer a promising energy storage solution due to their potential for high performance, cost-effectiveness, and sustainability. However, commercial viability is challenged by issues such as polysulfide migration, volume changes, uneven phase nucleation, limited ion transport, sluggish redox kinetics. Addressing these challenges requires insights into the structural, morphological, chemical evolution of phases, associated changes internal stresses, diffusion within battery. Such can only be obtained through real-time reaction monitoring battery's operational environment, supported molecular dynamics simulations advanced artificial intelligence-driven data analysis. This review provides an overview

ABSTRACT The urgent demand for renewable energy solutions, propelled by the global crisis and environmental concerns, has spurred creation of innovative materials solar thermal storage. Photothermal phase change (PTPCMs) represent a novel type composite material (PCM) aimed at improving storage efficiency incorporating photothermal into traditional PCMs encapsulating them within porous structures. Various encapsulation have been studied, including carbon, expanded graphite, ceramics, but issues like brittleness hinder their practical use. To overcome these limitations, flexible PTPCMs using organic polymers—like foams, hydrogels, wood—have emerged, offering high porosity lightweight characteristics. This review examines recent advancements in preparation based on polymer supports through techniques impregnation situ polymerization, assessing impact different PCM performance clarifying mechanisms conversion heat Subsequently, most applications polymer‐based are systematically summarized, future research challenges possible solutions discussed. aims to foster awareness about potential promoting environmentally friendly practices catalyzing further this promising field.

Abstract Alkali metal chalcogen batteries (such as lithium–sulfur/selenium, sodium–sulfur systems, abbreviated Li‐S/Se and Na‐S) have become an important direction for the next generation of high‐energy due to their ultra‐high theoretical energy density cost advantages, but problem rapid capacity decay needs be solved urgently. Covalent organic frameworks (COFs) provide a new idea improving battery performance high specific surface area tunable structure: porous structure can sufficient electrochemical reaction sites optimize ion transport paths, thereby charge‐discharge efficiency rate performance. In this paper, research progress COFs in alkali is systematically reviewed.

Lithium-sulfur (Li-S) batteries have attracted much attention due to their high theoretical specific capacity and low price, while there are still a series of problems, such as the shuttle effect lithium polysulfide (LiPS) fragility cathode structures, which need be addressed. In order solve above use binder is an effective approach. Therefore, in this work, poly(acrylic acid) (PAA), poly(vinyl alcohol) (PVA) boric acid (BA) were used jointly construct novel polymer for sulfur cathodes. The designed PAA-PVA-BA copolymer (PPB) contains large number polar functional groups, strong adsorption LiPS can effectively inhibit LiPS. Meanwhile, PPB also demonstrates good electrolyte compatibility thermal stability, provides support efficient stable operation Li-S batteries. with excellent cycling performance, completing 200 cycles at current density 0.5 C retention rate 84.4%. performance assembled was greatly improved, maintaining discharge 408.1 mA h g
