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。无锂金属的Li2S-石墨全电池已通过在电池组装过程中进行的化学锂化工艺成功制造。大面积的袋型电池已经实现，使其成为一种有前景的适用于Li2S全电池的锂化方法。该部分工作已在Journal of Power Sources上发表论文。另一方面，开展了Li2S/碳纳米粒子的合成研究。这样，实现了正极复合材料中Li2S的高重量比。该方法可应用于各种类型的集流体，使其应用​​领域更加广阔。该部分工作已投稿至高影响因子期刊并正在进行中。
