Modeling of Characteristics of Lithium-Sulfur Batteries Based on Experimental Evaluation of Electrochemical Properties of Electrode Materials

To model the characteristics of lithium-sulfur batteries based on the experimental evaluation of the electrochemical properties of electrode materials, the software "Battery Designer", included in the software package “ElChemLab”, was developed. The possibilities of software are described. The specific energy of lithium-sulfur batteries is compared for different surface capacitances of a positive electrode and for different amounts of electrolyte.

Peculiarities of Obtaining and Electrochemical Properties of Lithium-Ion Battery Cathode Materials Based on Iron(II)-Lithium Orthosilicate

Various strategies for the synthesis of promising electrode materials for lithium-ion battery (LIB) based on iron(II)-lithium orthosilicate (Li2FeSiO4) using widely distributed, environmentally friendly and inexpensive starting materials are considered. The materials obtained are multicomponent electroactive composites that include, in addition to the main lithium accumulating component, also auxiliary structure-forming and electrically conductive components based on the products of the pyrolytic decomposition of organic compounds.

High-voltage Cathode Material Based on LiCoVO? for Lithium-Ion Battery: Development and Research

This paper discusses the prospects for developing a cathode material based on the cobalt(II)-lithium vanadate(V) (LiCoVO4) for a lithium-ion battery, an approach to its preparation and features of the electrochemical behavior.

Manganese-Doped Titanium Dioxide with Improved Electrochemical Performance for Lithium-Ion Batteries

Within the work, an influence of manganese dopant on electrochemical performance of anatase titanium dioxide (Mn/Ti = 0.05; 0.1; 0.2) had been investigated. It was established that incorporation of Mn3+ into the TiO2 lattice results in the formation of Ti1 ? xMnxO2 solid solution and increased anatase unit cell volume from 136.41 A3 (undoped sample) to 137.25 A3 (Mn/Ti = 0.05). The conductivity of doped TiO2 rises up to two orders in magnitude.
