How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Maryam Tahertalari works at the Departments of Semiconductor and Ceramic Engineering, University of Materials and Energy Research Center (MERC), Iran. Maryam does research on Lithium/Sodium-ion/Lithium-Sulfur batteries using computational (DFT) and experimental methods.
The improvement of intercalation electrodes, especially the cathodes, for Li-ion and Na-ion batteries requires a deep understanding of the relationships between the properties of the active materials and the variables introduced by the electrode/cell manufacturing strategies (e.g. carbon-based additives, binders, etc.). Starting from the specific e...
Li2FeSiO4 (LFS) has received remarkable attention due to its high thermal stability, environmental benignity, low cost, and low toxicity. However, the electrochemical performance of the material is restricted by achieving its high theoretical capacity (∼330 mA h g−1). Doping is a potentially effective method to enhance the electrical conductivity a...
As a high-capacity cathode material with a considerable cycle life, lithium metal orthosilicates have attracted much attention. In this paper, Li2FeSiO4, Li2FeSiO4−xClx and Li2FeSiO4−xFx are successfully synthesized via solid-state method. Li2FeSiO4−xFx is also composited with reduced graphene oxide (rGO). The X-ray diffraction patterns show 0.2% e...
Understanding underlying mechanisms of charge-discharge behaviour of batteries, especially the intercalation Li-ion and Na-ion ones, is obligatory to develop and design the energy storage devices. The behaviour of the voltage-capacity/time (V-C/T) diagram is one of the most critical issues which should be understood. This paper aimed to understand...
This paper proposes a mathematic relationship between obtained capacity and the corresponding current rate for the Li‐S and Na‐S conversion batteries. Using experimental data ondifferent conditions ofthe Li/Na‐S batteries, taken from literature, it is established that the inverse value of obtained capacity is changing linearly with respect tosquare...
