Biography

Dr. Yujing Bi is a material scientist in Battery Materials & Systems group at Pacific Northwest National Laboratory. He has expertise and experience in the fundamental study of battery materials, scaling up of new battery materials, electrode processing and pouch cell technologies, practically in the cathode field. Dr. Bi studied the mechanical degradation behavior of single crystal Ni-rich and published a paper on Science as cover. He developed facility for scaling up cathode materials and has successfully scaled up the patented synthesis approach for single crystal Ni-rich cathode materials. Dr. Bi has more 40 peer-viewed papers and holds 17 granted and pending patents.
