在本文中，我们报告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可实现最佳的全电池平衡。事实上，我们证明该电池在平均电压为 1.4 V 时具有约 280 mAh g(-1) 的非常稳定的容量。据我们所知，该电池是无锂金属硫电池的罕见例子之一。考虑到所使用的电极的高理论容量，我们相信这里报道的电池作为高能、安全和低成本的电动汽车电源可能具有潜在的意义。
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.
