Abstract Alkaline metal ion batteries, such as lithium‐ion batteries have been increasingly adopted in consumer electronics, electric vehicles, and large power grids because of their high energy density, power density and working voltage, and long cycle life. Phosphorus‐based materials including phosphorus anodes and metal phosphides with high theoretical capacity, natural abundance, and environmental friendliness show great potential as negative electrodes for alkaline metal ion batteries. In this review, based on the understanding of the storage mechanism of alkali metal ions, the scientific challenges are discussed, the preparation methods and solutions to address these challenges are summarized, the application prospects are demonstrated, and finally possible future research directions of phosphorus‐based materials are provided.
