DESCRIPTION:StorageX is pleased to be kicking off its monthly StorageX grou
 p meetings.  The objective of these group meetings is to create an opportu
 nity for sharing research updates\, sharing of ideas\, and for informal so
 cial exchange of the StorageX ecosystem\, analogous to a research group me
 eting. \n\nWe invite the students\, researchers and faculty of the Storage
 X Seed fund awards to attend and give a semi-annual update on their resear
 ch. The meetings are held hybrid. Lunch is provided.\n\nSpeaker\n\nZhelong
  Jiang\, PhD\, Associate Scientist\nSLAC-Stanford Battery Center\, Applied
  Energy Division\,\nSLAC National Accelerator Laboratory\n\n"Harnessing Ir
 reversible Anion Redox to Engineer Crystal Disorder and Improve Electrode 
 Stability"\n\n \n\nAbstract:\n\nA new strategy of preparing electrode mate
 rials with unconventional crystal ordering will be shown where irreversibl
 e anion redox is harnessed to induce topotactic structural evolution. Usin
 g this strategy\, partially disordered layered Ni-rich cathode is created 
 and shown to be electrochemically stable with a high Li inventory. The not
 orious c-collapse behavior\, which happens in virtually all layered lithiu
 m-ion battery cathodes at high states-of-charge that degrades battery perf
 ormance\, is absent in the disordered layered cathode. As a result\, a com
 bination of high specific capacity and long cycle life is achieved. Such a
 pproach of reaction pathway engineering can be used in both synthesis and 
 electrochemical activation to prepare future generations of battery electr
 ode materials.\n\nSpeaker's bio:\n\nDr. Zhelong Jiang is an Associate Scie
 ntist at the SLAC-Stanford Battery Center\, working in the development of 
 new materials chemistries for the next-generation of energy storage techno
 logies. Prior to joining the Batter Center\, he was postdoc at Stanford Un
 iversity working with Prof. William Chueh\, where he worked on the lithium
 -ion battery cathodes research. He specializes in the development and adva
 nced characterization tools\, such as diffraction and spectroscopy techniq
 ues\, to understand the redox mechanism and structural changes during the 
 electrochemical de-/lithiation of electrodes. He obtained his Ph. D. in Ma
 terials Science and Engineering from the University of Illinois at Urbana-
 Champaign\, supervised by Prof Daniel Shoemaker\, where he works on deciph
 ering synthesis kinetics and mechanisms during the materials formation. He
  received his bachelor’s degree in Materials Engineering at Nanyang Tech
 nological University\, Singapore\, where he worked with Prof. Zhong Chen i
 n the fabrication of photocatalytic nanomaterials.
