Gao Jian

I graduated from the Institute of Physics, Chinese Academy of Sciences with a doctor's degree. My main research areas are lithium-rich manganese-based cathodes with high rate, high capacity, and long cycle life; and mixed ionic-electronic conductive interfaces for all-solid-state batteries. My research is characterized by utilizing multi-scale calculations combined with machine learning to study the structure-performance relationships of key materials in lithium-ion batteries, and guiding experimental verifications.

Secondary batteries are the most promising energy storage technology for the next generation, holding significant importance for electric vehicles and large-scale energy storage. Given that the research and development of battery materials and devices involve the multiscale interactions and material performance optimization of multiple elements, phases, and microstructures, the traditional material research and development model characterized by a trial-and-error approach with a development cycle of up to 20 years is unable to meet the urgent industrial demand for new materials. I aim to utilize the materials genome strategy, integrating materials computation, data analysis, and intelligent data mining with traditional material preparation and characterization techniques. My research focuses on exploring the universal and characteristic structure-performance relationships of key materials in lithium-ion batteries, as well as the structure-performance relationships of multi-dimensional and multi-scale interfaces. Rational design of key materials and interfacial structures for lithium-ion batteries with high capacity, high rate, and high stability is also a priority. Currently, my main focus is on the design of mixed ionic-electronic conductive materials and solid-state interface modification, as well as the design, modification, and application of lithium-rich manganese-based layered cathode materials in high-energy secondary solid-state batteries.
