| Description |
Structural and electrochemical characteristics of nanosized LiNi0,5Mn1,5O4 synthesized by means of a citric acid aided route are presented. It is found that materials treated at 800 °C consist of the maximal amount of the disordered face-centered cubic phase. Galvanostatic discharge curves registered at various discharge currents (147-5800 mA·g – 1 or 1-40 C) prove the excellent high-rate performance of the samples studied. Specifically, the sample treated at 800 °С endures a load of 40 C delivering the reversible specific capacity of 34 mAh·g – 1. Such results have never been attained with LiNi0,5Mn1,5O4 electrodes prepared using standard techniques and overwhelms all existing data published to date. This remarkable result makes evident excellent prospects of non-solid-state routes for obtaining electrode materials for heavy-duty lithium-ion batteries of new generation. |
