Owing to the nanometer size range, Quantum Dots (QDs) have exhibited unique physical and chemical properties which are favourable for different applications. Especially, due to their quantum confinement effect, excellent optoelectronic characteristics is been observed. This considerable progress has not only uplifted the singular usage of QDs, but also encouraged to prepare various hybrid materials to achieve superior efficiency by eliminating certain shortcomings. Such issues can be overcome by compositing QDs with polymers. Via employing polymer composite with QDs (PQDs) for supercapacitor applications, adequate conductivity, stability, excellent energy density, and better specific capacitance is been achieved which we have elaborately discussed in this review. Researchers have already explored various types of polymer nanocomposite with different QDs such as carbonaceous QDs, transition metal oxide/sulphide QDs etc. as electrode material for supercapacitor application. Synthesis, application outcome, benefits, and drawbacks of these are explained to portray a better understanding. From the existing studies it is clearly confirmed that with using PQDs electrical conductivity, electrochemical reactivity, and the charge accumulation on the surface have prominently been improved which effected the fabricated supercapacitor device performance. More comprehensive fundamentals and observations are explained in the current review which indicates their promising scopes in upcoming times.
由于量子点（QDs）处于纳米尺寸范围，它们展现出了独特的物理和化学性质，这有利于不同的应用。特别是，由于其量子限制效应，观察到了优异的光电特性。这一显著进展不仅提升了量子点的单一用途，还促使人们制备各种混合材料，以通过消除某些缺点来实现更高的效率。通过将量子点与聚合物复合可以克服此类问题。通过将量子点与聚合物的复合材料（PQDs）用于超级电容器应用，可实现足够的导电性、稳定性、优异的能量密度和更好的比电容，我们已在本综述中对此进行了详细讨论。研究人员已经探索了各种类型的聚合物纳米复合材料，其中包含不同的量子点，如碳质量子点、过渡金属氧化物/硫化物量子点等，作为超级电容器应用的电极材料。对这些材料的合成、应用成果、优点和缺点进行了解释，以便更好地理解。从现有研究中可以清楚地证实，使用PQDs显著提高了电导率、电化学反应性以及表面的电荷积累，这影响了所制造的超级电容器器件的性能。当前的综述解释了更全面的基本原理和观察结果，这表明它们在未来具有广阔的应用前景。
