In this paper, we report a lithium-ion battery employing a lithium sulfide cathode and a silicon-based anode. The high capacity of the silicon anode and the high efficiency and cycling rate of the lithium sulfide cathode allowed optimal full cell balance. We show in fact that the battery operates with a very stable capacity of about 280 mAh g(-1) at an average voltage of 1.4 V. To the best of our knowledge, this battery is one of the rare examples of lithium-metal-free sulfur battery. Considering the high theoretical capacity of the employed electrodes, we believe that the battery here reported may be of potential interest as high-energy, safe, and low-cost power source for electric vehicles.
在本文中，我们报道了一种采用硫化锂阴极和硅基阳极的锂离子电池。硅阳极的高容量以及硫化锂阴极的高效率和循环速率实现了全电池的最佳平衡。事实上，我们表明该电池在平均电压为1.4V时，以约280 mAh g(-1)的非常稳定的容量运行。据我们所知，这种电池是无锂金属硫电池的少数例子之一。考虑到所使用电极的高理论容量，我们认为本文报道的电池作为电动汽车的高能、安全和低成本电源可能具有潜在的吸引力。
