Abstract To mitigate the environmental impact of improper disposal spent LiFePO 4 batteries and reduce resource waste, development recycling technologies is paramount importance. Meanwhile, olivine‐structured NaFePO in sodium‐ion has received great attention, due to its high theoretical specific capacity 154 mAh g −1 excellent stability. However, olivine only can be synthesized from . Accordingly, this proposal, developing continuous flow electrochemical solid‐liquid reactor‐based metal ion insertion technology utilize FePO , recycled synthesize Additionally, by employing I − as reducing agent, successfully with a discharge‐specific 134 at 0.1C remarkable retention rate 86.5% after 100 cycles 0.2C. And reasons for sodium deficiency NFP are elucidated through first‐principles calculations. Furthermore, kinetics solid‐solution reaction 2 (Na 2/3+β PO → Na 1‐α ) mechanism improve cycling sensitive temperature. Utilizing minimal amount agent reactor, synthesis achieved. This innovative approach offers new, cost‐effective, environmentally friendly strategy preparing
