IAS held the 4th Distinguished Scholars Lecturing Program at Room L1-503 of the Science and Engineering Building on November 8th with the presence of research scientist Xingke Cai, Ye Zhou, Wu Li and students from IAS.

Prof. Haoshen Zhou, who is a professor at Nanjing University and is awarded as the Chang Jiang Scholar of Ministry of Education, was invited to give a lecture entitled "Development of next-generation secondary batteries - lithium-air batteries, ithium-sulfur batteries and sodium-ion batteries". Prof. Zhou is primarily engaged in research on lithium-ion battery, sodium-ion battery, lithium-sulfur battery, lithium-air battery, solid-state battery and lithium-liquid-flow battery. In this report, he discussed the development trend and progress of lithium-air batteries, lithium-sulfur batteries and sodium-ion batteries, as well as the mechanism research and industrialization. Prof. Zhou noted that lithium-air batteries, lithium-sulfur batteries, and sodium-ion batteries with ultra-high theoretical energy density and low material cost and environmentally friendly materials would inspire people to achieve the goal of higher energy density in secondary batteries to seek new energy storage systems to get higher energy density in secondary batteries. However, there are many problems to be solved, so Prof. Zhou hoped that the young could study hard and devote themselves to scientific research.

The lecture ended at 11:40. Lecture 4 of Distinguished Scholars Lecturing Program made teachers and students understand secondary batteries and widen their academic horizon.
