Spring-like superstructures consisting of layered tin(IV) hydrogen phosphate nanodisks can be obtained via a one-pot solvothermal reaction of tin tetrachloride and phosphoric acid in ethanol. These superstructures are active anode materials for the lithium-ion battery.

Lithium iron orthosilicate (Li2FeSiO4) with Pmn21 space group is theoritically investigated as a chathode material of Li-ion batteries using density functional theory (DFT) calculations. PBE-GGA (+USIC), WC-GGA, L(S)DA (+USIC) and mBJ+LDA(GGA) methods under spin-polarization ferromagnetic (FM) and anti-ferromagnetic (AFM) procedure are used to investigate the material properties, includin...

Chemical energy storage using batteries will become increasingly important for future environmentally friendly ('green') societies. The lithium-ion battery is the most advanced energy storage system, but its application has been limited to portable electronics devices owing to cost and safety issues. State-of-the-art LiFePO4 technology as a new cathode material with surprisingly high charge-dis...

Liquid carbonate-based electrolytes are widely used in lithium ion batteries today. Dry polymer electrolytes are potential candidates for use in secondary lithium batteries because of ease of fabrication, good electrochemical stability, low flammability and toxicity with the ability to form good interfacial contact with electrodes. Conductivity and mechanical properties of dry electrolytes, how...

The need for development and deployment of reliable and efficient energy storage devices, such as lithium-ion rechargeable batteries, is becoming increasingly important due to the scarcity of petroleum. Lithium-ion batteries operate via an electrochemical process in which lithium ions are shuttled between cathode and anode while electrons flowing through an external wire to form an electrical c...

Since sensor nodes use batteries as their source of energy, energy-based routing becomes an important requirement to extend network lifetime. This routing is done using the nodes remaining energy information. Nonetheless, this information cannot be estimated using built-in primitives in nodes powered by a lithium-ion battery. The reason is that primitives rely on the decreasing battery voltage ...

Lithium ion (Li-ion) batteries have been widely used in various kinds of applications, including consumer electronics, green energy systems and electrical vehicles. Since the charging method has a significant influence on the performance and lifetime of Li-ion batteries, an intelligent charging algorithm which can properly determine the charging current is essential. In this study, a fuzzy-logi...
