Sodium-ion batteries (SIBs), an emerging type of sustainable battery, still need to be recycled for environmental and economic reasons. Strategies to recycle spent SIBs should be made during the initial stages of commercialization to ensure that SIBs are designed for ease of recycling, efficiency and low operation costs. This Perspective article summarizes the material components of SIBs, discusses strategies for their recycling and outlines the associated challenges and future outlook of SIB recycling.
