摘　　要：含钒石煤是我国的一种新型钒矿资源,本文用从石煤中提取的V_2O_5研制全钒氧化还原电池。该电池是一种新型储能材料,它用由V_2O_5制备的VOSO_4溶液作电极活性材料。一系列充放电试验结果表明,该电池具有良好的化学性能。Vanadium-bearing carbonaceous shale is a new type of vanadium ore. All-vanadium redox flow cell is a new energy storage unit. The battery has been developed. Vanadyl sulfu-ric (VOSO4) acid solutions prepared with V2O5 extracted from carbonaceus shale are em-ployed in both half-cells as the electrode active materials. An experimental cell was con-structed. A series of charge-discharge experiments have been preformed. The results indi-cate that cell have a good electrochemical performance during charging-discharging.
