Abstract: The electrochemical behavior of mesoporous tin phosphate (SnP2O7) was studied for possible application as the anode material in lithium-ion batteries. This tin phosphate material which was prepared via a surfactant templating method and calcined at 400째C, showed an average pore size distribution of 18 nm. Cyclic voltammogram and differential capacity plot analyses indicated irreversible reduction of tin phosphate to lithium phosphate and tin upon initial reaction with lithium and subsequently followed by the reversible alloying and de-alloying reaction of lithium with tin. The mesoporous tin phosphate exhibited initial reversible capacity of 265 mAh/g and good capacity retention of 188 mAh/g upon reaching the 10th cycle. Keywords: mesoporous tin phosphate, anode material, charge-discharge, capacity, lithium-ion battery
