Sigray releases two new applications notes demonstrating the QuantumLeap’s powerful synchrotron-like capabilities:

  • Battery Bond Lengths as a Function of Cycling: describes evaluating the Mn, Co, and Ni bonds of a NMC LIB, finding the Ni-O suffers from Jahn-Teller distortion whereas the local environment is preserved.
  • Speciation of Cobalt in NMC Batteries: demonstrates the synchrotron-like quality of Sigray’s data to enable Co speciation of an NMC LIB, finding three isobetic points of Co XANES. PCA and ITTFA reconstruction of the XANES show that two unique species of Co are seen in four NMC samples.
