Polypyrrole/nickel phosphide (PPy/Ni₂P) composites were synthesized through a facile two-step method. The results show that when there is 30% Ni₂P in PPy/Ni₂P (active material 3 mg), the prepared composites possess uniform morphology, which composed of large quantities of broccoli-like PPy microstructures (average dimension of about 200 nm) and Ni₂P spherical particles (average diameters of 250 nm). It achieves a higher specific capacity for 476.5 F g⁻¹ at a current density of 1 A g⁻¹ in a three-electrode system, even after 3000 cycles the capacity maintained 89%. The excellent electrochemical performance of PPy/Ni₂P composites may be due to the good dispersion and uniform morphology of Ni₂P nanoparticles. In addition, the synergistic effect between PPy and Ni₂P nanoparticles also dramatically improves the electrochemical properties of the composites.

The as-prepared PPy/Ni₂P electrodes exhibit higher specific capacitance, smaller charge-transfer resistance, and superior cycle stability.

通过简便的两步法合成了聚吡咯/磷化镍（PPy / Ni ₂ P）复合材料。结果表明，当PPy / Ni ₂ P（活性物质3 mg）中Ni ₂ P含量为30％时，制备的复合材料具有均匀的形貌，其由大量的西兰花状PPy微观结构组成（平均尺寸约为200 nm）。 ）和Ni ₂ P球形颗粒（平均直径250 nm）。在三电极系统中，在1 A g ^-1的电流密度下，即使达到476.5 F g ^-1，其比容量也更高，即使经过3000次循环，容量仍保持89％。PPy / Ni ₂的优异电化学性能P复合材料可能是由于Ni ₂ P纳米颗粒具有良好的分散性和均匀的形貌。此外，PPy和Ni ₂ P纳米颗粒之间的协同作用还显着改善了复合材料的电化学性能。

所制备的PPy / Ni ₂ P电极具有较高的比电容，较小的电荷转移电阻和优异的循环稳定性。
