Theoretical Calculations Facilitating Catalysis for Advanced Lithium-Sulfur Batteries
Lithium-sulfur (Li-S) batteries have emerged as one of the most hopeful alternatives for energy storage systems. The poor conductivity of sulfur cathodes induces sluggish redox kinetics. The shuttling of polysulfides incurs the heavy failure of electroactive substances. Tremendous efforts in experiments to seek efficient catalysts have achieved significant success.

The Rheological Phase Reaction Method
The term “rheology” stands for the study of a material’s flow behavior under applied deformation forces or stress. The Rheological Phase Reaction (RPR) method is considered a “pollution-less method” to prepare any metal oxides with high crystallinity, phase purity, and fewer agglomerations depending on the proper raw materials and the right temperature conditions are being chosen.

The Gel-State Electrolytes in Zinc-Ion Batteries
Zinc-ion batteries (ZIBs) are receiving increasing research attention due to their high energy density, resource abundance, low-cost, intrinsic high-safety properties, and the appropriate plating/stripping voltage. Gel-state electrolytes possess merits of having a wide electrochemical window, good flexibility, superior water retainability, and excellent compatibility with aqueous electrolytes, which makes them potential candidates for flexible batteries. However, the practical applications of ZIBs with gel-state electrolytes still have some issues of water content easily dropping, poor mechanical stability, and the interface problem.

The beautiful world of biosensors
The biosensors have important role in science of chemical analysis in the field of electrochemical methods. Their application in rapid detection of toxins in types, we consume in our daily lives, is particularly useful for public health. The main characteristics of evaluation of biosensors is the high sensitivity, high selectivity, the quick response and the reusability. Analysis of the real samples need additionally a method of evaluating the rate of recovery that is the fractional difference of signal between real and simulated samples. The advantages of the use of biosensors are part of the easy construction, portability and low cost. The provision of analytical results of biosensors is similar to that of other far more expensive methods of instrumental chemical analysis.

Synthesis of Conducting Polymers
Conductive polymers (CPs) are a class of organic compounds that belong to a large group of electrochemically active polymers. They have been actively studied for more than 40 years, beginning with the discovery of the conductive properties of halogen-substituted polyacetylene and the preparation of polypyrrole.

Surfactants as Performance-Enhancing Additives in Supercapacitor Electrolyte Solutions
Wetting the surface area of an electrode material as completely as possible is desirable to achieve optimum specific capacity of an electrode material. Keeping this surface area utilized even at high current densities and even when inside small pores is required for high capacitance retention. The addition of surfactants at small concentrations to aqueous supercapacitor electrolyte solutions has been suggested as a way to improve performance in terms of capacitance, capacitance retention at increased current density and stability. Effects are pronounced with carbon materials used in electrochemical double-layer capacitors; they are also observed with redox materials.

Structural Supercapacitors
Structural supercapacitors (SSCs) are multifunctional energy storage composites (MESCs) that combine the mechanical properties of fiber-reinforced polymers and the electrochemical performance of supercapacitors to reduce the overall mass in lightweight applications with electrical energy consumption. These novel MESCs have huge potentials, and their properties have improved dramatically since their introduction in the early 2000’s. However, the current properties of SSCs are not sufficient for complete energy supply of electrically driven devices.

Status of Health Estimation Methods
As the backup power supply of power plants and substations, Valve Regulated Lead Acid (VRLA) batteries are the last safety guarantee for the safe and reliable operation of power systems, and the batteries status of health(SOH)directly affects the stability and safety of power system equipment. In recent years, due to the aging and failure of VRLA batteries, some serious safety accidents have been caused, so it is very necessary to accurately evaluate the health of batteries.
