Conventional lithium‐ion batteries have approached their capacity and energy density limits. Use of lithium metal anode can enable high‐energy batteries. However, the safety hazards and lithium dendrite formation associated with lithium metal require safe electrolytes to replace flammable liquid ones. In recent years, solid‐state electrolytes have attracted tremendous attention. Among them, composite polymer electrolytes (CPEs) with different constitutions have the unique advantages of low interfacial resistance, high ionic conductivity, and flexible characteristics. Here, the basic properties and analysis methods related to CPEs are discussed. Following that, the components added into the polymer matrix, such as organic solvents, nanostructured ceramics, and fast‐ion‐conductive inorganics are classified. CPEs used in low‐cost Na and K batteries are briefly discussed. It is hoped that the review can supply both advances and fundamentals to the researchers in this field and provide guidance for the development of CPEs for lithium battery systems, and beyond.

“…The ideal performance characteristics of energy storage devices are high energy density, high power density, long cycle life, low cost and high safety [ 1 ]. Among the existing secondary batteries, lithium-ion batteries have been industrialized, but their high cost, low practical energy density (100–200 Wh kg −1 ) and poor safety performance limit their application [ 2 , 3 ]. In order to meet the energy storage needs of current society, it is necessary to design and develop other batteries with lower cost, longer cycle life and higher energy density and power density.…”

Lithium metal batteries have achieved large-scale application, but still have limitations such as poor safety performance and high cost, and limited lithium resources limit the production of lithium batteries. The construction of these devices is also hampered by limited lithium supplies. Therefore, it is particularly important to find alternative metals for lithium replacement. Sodium has the properties of rich in content, low cost and ability to provide high voltage, which makes it an ideal substitute for lithium. Sulfur-based materials have attributes of high energy density, high theoretical specific capacity and are easily oxidized. They may be used as cathodes matched with sodium anodes to form a sodium-sulfur battery. Traditional sodium-sulfur batteries are used at a temperature of about 300 °C. In order to solve problems associated with flammability, explosiveness and energy loss caused by high-temperature use conditions, most research is now focused on the development of room temperature sodium-sulfur batteries. Regardless of safety performance or energy storage performance, room temperature sodium-sulfur batteries have great potential as next-generation secondary batteries. This article summarizes the working principle and existing problems for room temperature sodium-sulfur battery, and summarizes the methods necessary to solve key scientific problems to improve the comprehensive energy storage performance of sodium-sulfur battery from four aspects: cathode, anode, electrolyte and separator.

“…In recent years, it has become more and more difficult for the current commercial lithium-ion batteries (LIB), due to their relatively low theoretical energy density limits (200–300 Wh/kg), to meet the ever-growing demands of society’s electrical energy storage, including portable electronic devices, electric vehicles, and smart grid storage applications [ 1 , 2 , 3 ]. Therefore, novel rechargeable batteries with a large charge storage capacity and a high energy density are urgently needed [ 4 , 5 , 6 , 7 , 8 , 9 ].…”

Metal-N4@Graphene as Multifunctional Anchoring Materials for Na-S Batteries: First-Principles Study

et al. 2021

Developing highly efficient anchoring materials to suppress sodium polysulfides (NaPSs) shuttling is vital for the practical applications of sodium sulfur (Na-S) batteries. Herein, we systematically investigated pristine graphene and metal-N4@graphene (metal = Fe, Co, and Mn) as host materials for sulfur cathode to adsorb NaPSs via first-principles theory calculations. The computing results reveal that Fe-N4@graphene is a fairly promising anchoring material, in which the formed chemical bonds of Fe-S and N-Na ensure the stable adsorption of NaPSs. Furthermore, the doped transition metal iron could not only dramatically enhance the electronic conductivity and the adsorption strength of soluble NaPSs, but also significantly lower the decomposition energies of Na2S and Na2S2 on the surface of Fe-N4@graphene, which could effectively promote the full discharge of Na-S batteries. Our research provides a deep insight into the mechanism of anchoring and electrocatalytic effect of Fe-N4@graphene in sulfur cathode, which would be beneficial for the development of high-performance Na-S batteries.
