| description | <p></p><div> <p>This study reports hybrid cathodes formation by cation substitution in which Li<sup>+</sup> substitution has been considered for Na<sup>+</sup> in the structure of Na<sub>(2-x)</sub>Li<sub>x</sub>FeP<sub>2</sub>O<sub>7</sub> (x=0, 0.6) to form Na<sub>1.4</sub>Li<sub>0.6</sub>FeP<sub>2</sub>O<sub>7</sub> cathodes. Na<sub>(2-x)</sub>Li<sub>x</sub>FeP<sub>2</sub>O<sub>7</sub> (x=0, 0.6) cathodes were synthesized using the solid-state synthesis technique and characterized by various methods. The structural analysis (XRD, FE-SEM) indicates that the submicron-sized, phase pure, and crystalline materials having irregular morphology have been developed. Moreover, Li<sup>+</sup> substitution does not alter the triclinic parent structure of Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub>. Thermogravimetric analysis (TGA) shows that Li<sup>+</sup> substitution into Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub> improves its thermal stability up to 550 °C with only ∼5 % weight loss. The electrochemical performance of Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub> and Na<sub>1.4</sub>Li<sub>0.6</sub>FeP<sub>2</sub>O<sub>7</sub> in both lithium (Li) and sodium (Na) half-cells is investigated using different electrochemical techniques. It is noticed that Na<sub>1.4</sub>Li<sub>0.6</sub>FeP<sub>2</sub>O<sub>7</sub> is electrochemically active both in lithium (Li) and sodium (Na) cells with promising cyclability. However, compared with Na<sub>2</sub>FeP<sub>2</sub>O<sub>7,</sub> Na<sub>1.4</sub>Li<sub>0.6</sub>FeP<sub>2</sub>O<sub>7</sub> suffers from inferior electrochemical performance, which might be associated with the lattice distortion of Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub> due to Li<sup>+</sup> substitution having a lower ionic radius than the Na<sup>+</sup>. Considering Na<sub>2</sub>FeP<sub>2</sub>O<sub>7</sub> as a baseline material, a new hybrid Na<sub>1.4</sub>Li<sub>0.6</sub>FeP<sub>2</sub>O<sub>7</sub> cathode has been developed, which can be used to synthesize other new cathode materials with improved performance.</p> </div><p></p><h2>Other Information</h2> <p> Published in: ChemistrySelect<br> License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="http://dx.doi.org/10.1002/slct.202003658" target="_blank">http://dx.doi.org/10.1002/slct.202003658</a></p> |
