With the urgent demand for clean energy and the rapid development of modern electronic technology, there is increasing attention on green energy and novel energy storage technologies, particularly electrochemical water splitting and supercapacitors. The design of electrode materials with excellent catalytic and energy storage performance is of paramount importance. Layered double hydroxides (LDHs) have attracted strong interest from researchers due to their tunability in composition, structure, and morphology. Meanwhile, the introduction of oxygen vacancies into LDHs to enhance their catalytic and energy storage performance has been widely studied, yielding various effective results. This review summarizes the latest progress in the design and research of LDH-based electrode materials with oxygen vacancies for electrocatalysis and supercapacitors. Discussions are provided on the formation of oxygen vacancies and their enhancement of electrocatalytic and energy storage performance. Through the continuous efforts of scientists, LDH-based materials rich in oxygen vacancies have shown significant improvements in catalytic and energy storage performance, making them more competitive in modern applications.
