摘要
研究以普鲁士蓝类似物为前驱体通过固相法制备金属相硒化钼为正极的锂硫电池,旨在开发新型的锂硫电池正极材料。实验结果表明,在电流密度为0.1 C(1 C=1675 mA/g)时,首次充电比容量和放电比容量分别达到984 mAh/g和970 mAh/g。在0.5 C时,300圈后仍有351 mAh/g。试验结果为锂硫电池的商业化提供数据支撑,拓宽了锂硫电池正极材料的研究思路。
The paper uses prussian blue analogues as precursors to prepare lithium-sulfur batteries with metallic-phase molybdenum selenide as the cathode via a solid-phase method,aiming to develop new cathode materials for lithium-sulfur batteries.The experimental results show that at a current density of 0.1 C(1 C=1675 mA/g),the initial charge specific capacity and discharge specific capacity reach 984 mAh/g and 970 mAh/g,respectively.At 0.5 C,the specific capacity remains 351 mAh/g after 300 cycles.The test results provide data support for the commercialization of lithium-sulfur batteries and broaden the research ideas for cathode materials of lithium-sulfur batteries.
