Emerging presodiation strategies for long-life sodium-ion batteries

Sodium-ion batteries (SIBs) have attracted increasing attention as electrochemical energy storage in academic research and industrialization due to abundant reserves, low cost, and excellent power performance. Unfortunately, the commercial application is impeded by the low initial coulombic efficiency (ICE) and limited cycle life owing to largely irreversible loss of Na+, so the presodiation techniques have been crucial strategies to compensate capacity loss. For emerging technology, some reviews have summarized the presodiation methods according to mechanisms and their corresponding performance with specific applications in the past few years. However, there has rarely been sorted based on electrode materials systematically though the normal sequence is that electrode materials were selected first and then optimized for improved performance happened. Therefore, this review focus on the presodiation process and the performance from the perspective of electrode materials. In addition, the perspective of how to promote the further development of presodiation was described. We believe this review will provide a novel sight between electrode materials in SIBs and presodiation strategies and contribute to the rapid development and application of SIBs in the future.
