مستخلص: A ternary metal oxide, bismuth stannate and its carbon composite are prepared by a solution synthesis approach. The as-prepared materials are checked for phase purity by X-ray diffraction and characterized by various characterization techniques. The composite electrode performs better compared to pristine material when investigated as anodes for Li-ion batteries (LIBs). The use of an electrolyte additive leads to improved performance. High capacity of 960 mAh g−1is obtained at 100 mA g−1for LIBs. At a high-rate of 1000 mA g−1, 1250 stable cycles are observed with very good capacity retention, and the capacity is ∼475 mAh g−1at the end of the cycling. As investigated by different techniques, both conversion and alloying reactions are responsible for such high performance. The carbon network improves the conductivity and stabilize the intermediates formed during cycling. Further, the full cell studies with the composite anode and LiFePO4cathode show good performance.
