Manganese-Containing Supercapacitors for Future Energy Storage

Abstract

Due to the fast developing demand for storing new energy, as well as the practical need of the growing smart grid technologies, many researchers engage in nanoparticles to explore their energy storage potential. Supercapacitors become very popular in the past two decades for their high power density and long-term cycling stability. Manganese-containing electrode materials show many advantages in asymmetric supercapacitor devices. In this review, we will both provide a facile practice of building asymmetric supercapacitors in the lab and list some latest results in the field of Mn-containing electrode materials and find out the challenges that still lie there. From the review work, we hope to attract more material and energy system researchers to pay attention to these materials, make our contribution together and bring a brighter future to energy storage.
