摘　　要：Introduction of vacancies is a widely practiced method to improve the performance of active materials in differentenergy systems, such as secondary batteries, electrocatalysis, and supercapacitors. Because vacancies can generateabundant localized electrons and unsaturated cations, the incorporation of vacancies will significantly improvethe electrical conductivity, ion migration, and provides additional active sites of energy storage materials. Thisarticle systematically reviews different methods to generate oxygen, nitrogen, or selenium vacancies, and techniques to characterize these vacancies. We summarize the specific roles that vacancies play for the active materials in each type of energy storage devices. Additionally, we provide insights into the research progress andchallenges associated with the future development of vacancies technology in various energy storage systems.
