In this year, the new in-situ lithiation method was proposed. The lithium metal free Li2S-graphite full cell has been successfully fabricated through a chemical lithiation process which was conducted during assembling the cell. The pouch type cell with large area has been realized, making it a promising applicable lithiation method for Li2S full cell. This part of work has been published a paper in Journal of Power Sources.On the other hand, the synthesis of Li2S/carbon nanoparticles was developed. In this way, the high weight ratio of Li2S in the cathode composite was realized. This method can be applied in various kinds of current collectors, which makes it a broader application field. This part of work has been submitted to high impact factor journal and in process.

今年提出了新的原位锂化方法。通过在电池组装过程中进行的化学锂化工艺，成功制备了不含锂金属的li2s -石墨全电池。实现了大面积袋状电池，是一种很有前景的锂化方法。这部分工作已发表在《Journal of Power Sources》杂志上。另一方面，研究了Li2S/碳纳米颗粒的合成。从而实现了阴极复合材料中Li2S的高质量比。该方法可适用于各种集流器，具有更广阔的应用领域。这部分工作已经提交给高影响因子期刊，正在进行中。
