摘要：Considering the emerging demand of electrified vehicles and connected society, the development of battery is still extremely important. Capacity, power(charge, discharge), lifetime(cycle, shelf), safety(passive, active), cost, temperature dependence, reproducibility, and more...there are huge challenges for the demands, however, the original concept of Li-ion battery(LIB) has almost been matured through its 30 years of development. That is the critical reason why we need to explore new generation of batteries beyond the regular Li-ion system.

On the other hand, Materials Informatics(MI) has been showing its significant potential to make breakthroughs in materials R&D. The new approach will tell us unexpected candidate materials based on data-driven machine learning technologies. However, even this approach is so powerful, fundamentally it is not able to propose new materials beyond basic physical and chemical theory, needless to mention. We still need to make an evolution of battery by our own brains with new concepts.  

Then, where is the new frontier in battery? All-solid LIB, Li-sulfur, Li-air, Na-ion, Na-sulfur, Mg-ion, Zn-air, Zn-Ni, Al-air and redox flow...so many options have been proposed and, sometimes, disappeared. In this talk, some examples will be shown how scientists in the world and in our company struggled and tried to open the door to the new frontier. That is also the new challenges and expectations for MI how data-science can assist the battery materials R&D from untouched and realistic aspects.
