Tin‐based anode materials gained prominence in battery applications owing to their high theoretical capacity, less toxicity, and low cost. However, they suffer from huge capacity losses due to severe volumetric expansion up to 300%. Herein, Sn@C (20 wt% Sn) composite synthesized by single‐step combustion process showed good adherence of tin particles on graphite rich carbon which successfully minimizes pulverization with enhanced structural stability. The homogeneously dispersed tin nanoparticles exhibit a highly reversible capacity of 281 mA h g −1 at a current density of 300 mA g −1 with 98.6% capacity retention after 300 cycles.
