| Outline of Annual Research Achievements |
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.
