Phosphorus and tin phosphide based materials that are extensively researched as the anode for Na‐ion batteries mostly involve complexly synthesized and sophisticated nanocomposites limiting their commercial viability. This work reports a Sn4P3‐P (Sn:P = 1:3) @graphene nanocomposite synthesized with a novel and facile mechanochemical method, which exhibits unrivalled high‐rate capacity retentions of >550 and 371 mA h g−1 at 1 and 2 A g−1, respectively, over 1000 cycles and achieves excellent rate capability (>815, ≈585 and ≈315 mA h g−1 at 0.1, 2, and 10 A g−1, respectively).
