| Abstract: | MSnO_3(M=Ca,Sr,Ba) crystals with perovskite structures were synthesized by sol-gel method.Their electrochemical properties were characterized by constant current batteries tester using above crystals as active materials for the anodes of Li-ion batteries.The results showed that the initial discharge capacities of CaSnO_3, SrSnO_3 and BaSnO_3 were 894.3 mAh/g, 703.8 mAh/g and 673.6 mAh/g, the initial charge capacities were 418.3 mAh/g, 257.8 mAh/g and 224.8 mAh/g and the irreversible capacities were to be 53.2%, 63.3% and 66.6%, respectively. |
