1. Introduction. Conventional fuel-fired vehicles use the energy generated by the combustion of fossil fuels to power their operation, but the products of combustion lead to a dramatic increase in ambient levels of air pollutants, which not only causes environmental problems but also exacerbates energy depletion to a certain extent [1]
Electrochemical energy storage technologies have a profound influence on daily life, and their development heavily relies on innovations in materials science. Recently, high-entropy materials have attracted increasing research interest worldwide. In this perspective, we start with the early development of high-entropy materials and the
