Article Synopsis
- High-entropy ceramics, such as Sn(CoMgMnNiZn)O, show promising results for Li-ion batteries, demonstrating excellent cyclability and high specific capacity over 500 cycles.
- The stable electrochemical performance is attributed to the formation of an amorphous matrix during initial lithiation, which maintains atomic scale cation disorder while preventing the formation of disruptive metallic phases.
- This study highlights the potential for easy implementation of high-entropy materials in oxide anodes, showcasing their practicality for improving Li-ion battery technology.
Given the extensive efforts focused on protecting the environment, eco-friendly cathode materials are a prerequisite for the development of Na-ion battery technology. Such materials should contain abundant and inexpensive elements. In the paper, we present NASICON-NaFeMn(PO) ( = 0, 0.
View Article and Find Full Text PDFLiFePO₄ is considered to be one of the most promising cathode materials for lithium ion batteries for electric vehicle (EV) application. However, there are still a number of unsolved issues regarding the influence of Li and Fe-site substitution on the physicochemical properties of LiFePO₄. This is a review-type article, presenting results of our group, related to the possibility of the chemical modification of phosphoolivine by introduction of cation dopants in Li and Fe sublattices.
