DESCRIPTION:Abstract:\n\n \n\nAdvanced battery materials for next-generatio
 n technologies involve complex chemistries (at least pseudo-quaternary). T
 hese materials typically lie in systems where only a handful of compositio
 ns have been explored. Furthermore\, in cases where further substitutions 
 may prove useful\, only a few substituents have been considered in traditi
 onal battery development. To fully understand the impact of composition an
 d structure upon the battery properties\, thousands of samples are require
 d. Herein\, a suite of high-throughput (HTP) methods (a maximum total thro
 ughput of 892 samples/week) developed and utilized in the McCalla lab is p
 resented. HTP experiments include X-ray diffraction\, electrochemistry (to
  yield important metrics such as energy density\, cycling stability\, and 
 electrochemical stability window)\, electrochemical impedance spectroscopy
  (to determine ionic conductivity and stability against metallic anodes)\,
  and DC conductivity measurements. These methods\, all in high-throughput\
 , permit the systematic design of cathodes\, anodes and solid electrolytes
  for both Li- and Na-ion batteries.\n\nThis presentation will then demonst
 rate progress made in developing various components of advanced batteries 
 using our HTP experiments\, both showing improved performance and highligh
 ting new understanding about these materials. The Li- and Na-ion battery c
 omponents studied include cathodes and ceramic oxides as solid electrolyte
 s. In each case\, HTP screening of substituents (up to 59 dopants tested s
 imultaneously) yields materials with significantly improved properties and
  also greatly advances our fundamental understanding of the complex role o
 f composition in these systems.\n\n \n\n \n
