Fabrication of new materials with unique nanostructure has emerged as a potent strategy to enhance their properties for various applications. Presently, we report the successful incorporation of SnSe (a metal chalcogenide) into LaDySn₂O₇ (a pyrochlore) in order to enhance the electrochemical performance as well as stability of composite. The synthesized materials were characterized by various techniques to confirm the phase and morphology. A good pseudocapacitive behavior was observed through cyclic voltammetry. Galvanostatic charge/discharge profile of nanocomposite affirmed a specific capacitance of 1780 F/g at 0.1 A/g. Moreover, the fabricated electrode material showed an excellent specific power of 6157.411 W/kg at a current density of 0.3 A/g. An excellent electrochemical stability of the composite material after 2000 cycles was also observed. These properties make the fabricated material a potential candidate for supercapacitor applications.

具有独特的纳米结构的新材料的制造已成为一种有效的策略，可以提高其在各种应用中的性能。目前，我们报道了成功地将SnSe（一种金属硫属元素化物）掺入LaDySn ₂ O _7中（烧绿石），以增强复合材料的电化学性能和稳定性。用各种技术对合成的材料进行表征，以确认其相和形态。通过循环伏安法观察到良好的伪电容行为。纳米复合材料的恒电流充电/放电曲线证实了在0.1 A / g时的比电容为1780 F / g。此外，所制造的电极材料在0.3A / g的电流密度下显示出优异的比功率为6157.411W / kg。在2000次循环之后，还观察到复合材料的优异的电化学稳定性。这些特性使制造的材料成为超级电容器应用的潜在候选者。
