Abstract

Abstract: Tin-based anode materials are important components of lithium-ion batteries (LIBs) owing to their larger theoretical capacitance and lower working potential. However, the synthesis of tin-based anode materials is very complex, impeding their industrialization. In this work, tin dioxide nanoparticles were synthesized using sodium alginate hydrogel as a chelating agent for the ion-exchange reaction with tin tetrachloride. The resulting nano-tin dioxide was uniformly distributed with a porous structure morphology. The addition of sodium alginate at 0.1 g yielded a sample (SA-0.1) with a high reversible specific capacity, excellent multiplicative properties, and good cycling stability. After 702 cycles, the capacity of reversible discharge of the SA-0.1 maintained 621.1 mAh g −1 at the current density of 0.5A g −1, which cooperates with the facile synthesis method making the composite promising for commercialization.
