Representative Research
1. Solid state lithium batteries
The "rigid-flexible coupling" composited solid polymer electrolyte is designed which effectively solves the problems of single polymer electrolyte and single inorganic solid electrolyte. The as developed SSLBs utilizing the composited solid polymer electrolyte possesses outstanding characteristics of high safety, high specific energy and long life, which is the prior choice of power battery technology for new energy vehicles.
The first international industrial demonstration line has been built with an annual output of 10 MWh. The specific energy of polymer SLIBs can reach as high as 350 Wh/kg at present. The SLIBs have excellent cycle performance. Moreover, the energy density of solid lithium metal batteries based on solid polymer electrolyte can reach 520 Wh/kg, with a cycle life of more than 200 times. The SLIBs, as a specialized battery with high specific energy, high safety and high-pressure resistance, have been served as main power sources for deep-sea equipment such as Tianya, Haijiao, Wanquan, Fenghuang and Haidou, etc. The SLIBs demonstrate 10918 m deep-sea application in the Mariana Trench, and create a world record of 26 days of single diving operation. The scientific and technological achievements appraisal organized by Sinopec Federation conclude that the technology has reached the international leading level in the field of deep sea equipment. Moreover, the relevant technologies won the first prize of Natural Science of Qingdao City in 2017 and Shandong Province in 2018.
2. Perovskite Solar Cells
A new nearly cubic NH2CH=NH2PbI3 (FAPbI3) perovskite was presented for solar cells. This new FAPbI3 perovskite extremely attractive for next generation high-efficiency low-cost solar cells and now become the core material for high performance perovskite solar cells. In the research of film fabrication technology, methylamine (CH3NH2) induced defect-healing of CH3NH3PbI3 perovskite thin films was discovered. This study represents a new direction for commercial large-scale fabrication of perovskite films which is successfully adopted by GCL for commercial fabrication of perovskite devices with a size over 2000 cm2. The side reaction in the methylammonium- and formamidinium-mixed organic cation perovskite solution was pointed out which is greatly related to the stability issue of perovskite devices.
