“…On the other hand, there are many challenges in polymer-based Li-S batteries. Firstly, the developed polymer electrolytes have relatively low conductivity and can only be operated at high temperature (> 60 °C) [398][399][400][401]. Furthermore, due to the membrane structure, the ion diffusion path from polymer electrolyte to electrode is limited and therefore high loading sulfur cathodes are difficult to achieve [400,401].…”

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li-S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li-S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li-S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li-S publications to find the shortcomings of Li-S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li-S batteries are discussed.

“…Conductive polymers are polymers with highly unpaired (π) conjugated polymeric chains. In comparison to their bulk forms nanostructured conductive polymers, provide several advantageous features, such as large surface areas, improved mechanical properties for strain housing and shortened paths for charge/mass/ion transport [48]. Among the conducting polymers, polypyrrole (PPy), is one of the most widely studied electronic materials which have potential applications in drug delivery, sensors and corrosion protection [49,50].…”

Abstract. Nanosized particles have attractive characteristics, which have received considerable attention in the last decade. Polymeric nanoparticles (PNP)s are solid particles or particulate dispersions with size in the range of 10-1000 nm. Due to the very small size, the surface area is very large so the percentage of atoms or molecules on the surface is significantly increased, which is expected to have extensive applications in various fields such as drug delivery systems, biosensors, catalysts, nanocomposites, agriculture and environment. The aim of the present paper is to critically review enhancement in the field of synthesis and different application of novel PNPs in various area from drug delivery to composite fabrication. Literature sources were mainly taken from the publications of 2011 and later; though, for a basic depiction of the structural principles, older publications have also been cited.

and poly(3,4-ethylenedioxythiophene) (PEDOT). The highly conjugated polymer chains can be reversibly assigned electrochemical properties by a doping/dedoping process. [9][10][11] By regulating and controlling the level of doping, their conductivities can be tuned in a wide range, from 10 −10 to 10 4 S cm, spanning the entire range from insulators to semiconductors, to conductors. [12,13] Additionally, these conducting polymers retain the advantages of traditional polymers, such as low cost, convenient preparation, good affinity to many other materials, and high flexibility and durability. Recently, great efforts have been made to exploit the applications of conducting polymers as electrocatalysts for fuel cells and as electrode materials for supercapacitors. Considering the rapidly booming efforts undertaken in this cutting-edge research area, it is necessary to highlight the new discoveries and achievements in the past several years. Here, we introduce the latest advances in conducting-polymer-based materials for fuel cells and supercapacitors, and focus on the strategies employed to improve their electrocatalytic and electrochemical performance. Conducting-Polymer-Based Catalysts for Fuel CellsFuel cells are promising green energy-conversion devices that convert chemical energy of various fuels directly into electric energy under electrochemical redox reactions. This technology provides intriguing applications in portable energy sources [14,15] and has attracted increasing attention in recent years. [16][17][18][19] Such energy-conversion systems require highly efficient electrocatalysts to trigger the oxygen reduction reaction (ORR) that occurs at the fuel cell's cathode. Platinum/ carbon (Pt/C) composite is demonstrated to be the most efficient catalyst used for fuel cells. [20][21][22] However, high price, scarcity, poor utilization efficiency, and easy carbon monoxide poisoning greatly limit its commercial applications. [23] Therefore, development of low-cost, stable, and efficient electrocatalysts for ORR is a major challenge in the field of fuel cells. [24][25][26][27][28] Owing to their highly tunable conductivity, good electrocatalytic activity, and satisfactory electrochemical stability, conducting polymers are considered to be promising electrocatalyst materials for the ORR. [29] Initially, conducting-polymer-based electrodes were fabricated through direct casting of neutral To alleviate the current energy crisis and environmental pollution, sustainable and ecofriendly energy conversion and storage systems are urgently needed. Due to their high conductivity, promising catalytic activity, and excellent electrochemical properties, conducting polymers have been attracting intense attention for use in electrochemical energy conversion and storage. Here, the latest advances regarding the utilization of conducting polymers for fuel cells and supercapacitors are introduced. The strategies employed to improve the electrocatalytic and electrochemical performances of conducting-polymerbased materials are prese...
