The introduction of oxygen vacancies (Vo) in lithium–sulfur battery (LSB) catalysts is regarded as an effective approach to improving catalyst performance. However, the high activity of Vo is a double-edged sword, and their instability is usually ignored. Here, we report an “anchor vacancies” method...
