(Invited) Structure Design and Property Enhancement of Electrode Materials of Lithium-ion Battery

is communication will report our recent progresses made on the design and synthesis of electrode nanomaterials of lithium ion battery for efficient energy storage. Lithium-ion batteries (LIB) are widely used today. The fast development of high-technologies (such as 5G and artificial intelligence (AI)) and electric vehicles demands increasing as much as possible energy and power density of LIBs. The key issue is to develop electrode nanomaterials with high capacity and high rate property, as the property of both anode and cathode nanomaterials is determined by their structure, especially the surface structure which relates to the energy barrier of surface reaction and the density of lithium ion transportation. Based on a thorough analysis of structure-functionality, we have achieved to design and tune the structure and property of electrode nanomaterials, including anode of metal oxides (such as Co 3 O4, MnO) and cathode of lithium rich oxide, NCM and Layered/Spinel heterostructure nanomaterials. All the designed and well-controlled electrode materials were tested in LIB cells, and superior capacity, high rate property and excellent cycleability were confirmed.
