Nanostructured Transition Metal Chalcogenides as Materials in Lithium Ion Batteries

Hierarchically Nanostructured Transition Metal Oxides for Lithium‐Ion Batteries

Lithium-ion batteries (LIBs) have been widely used in the field of portable electric devices because of their high energy density and long cycling life. To further improve the performance of LIBs, it is of great importance to develop new electrode materials. Various transition metal oxides (TMOs) have been extensively investigated as electrode materials for LIBs. According to the reaction mecha...

Simulation of capacity loss in carbon electrode for lithium-ion cells during storage

A mathematical model was developed which simulates the self-discharge capacity losses in the carbon anode for a SONY 18650 lithium-ion attery. The model determines the capacity loss during storage on the basis of a continuous reduction of organic solvent and de-intercalation of ithium at the carbon/electrolyte interface. The state of charge, open circuit potential, capacity loss and film resist...

Protein-Transition Metal Ion Networks

Proteins obtained from agricultural sources were blended with divalent metal ions to see if binding reactions occurred between protein chains. Feather keratin, egg albumin, and wheat gluten showed elastic modulus increases of 2–3 times with addition of divalent transition metal ions Cu2þ and Zn2þ. Increasing concentrations of ions resulted in increased stiffness. Birefringence experiments perfo...

Synthesis of Lithium Ion Sieve Nanoparticles and Optimizing Uptake Capacity by Taguchi Method

Spinel-type of MnO2 nanoparticles which successfully synthesized by a hydrothermal process, have a required capacity for lithium uptake from liquid resources. Themost lithium adsorption capacity of 6.6 mmol/g of up to now was found to be an important limiting parameter for industrial applications. Therefore, increasing uptake capacity of these ion sieve...
