Abstract

NiS₂ is a cathode material found in primary batteries which operate at high temperature. Herein we report the in situ battery discharge study of a thermal battery cell which uses NiS₂ as a cathode, using simultaneous collection of powder neutron diffraction data and electrochemical data. Five different regions were observed upon battery discharge and the evolution of nickel sulfide phases has been studied. Four different nickel-containing phases are observed during discharge (NiS₂, NiS, Ni₃S₂ and Ni). A new discharge mechanism has been proposed which does not include Ni₇S₆. Multiphase quantitative Rietveld refinement has allowed the percentages of the phases to be monitored during discharge. High intensity synchrotron powder X-ray diffraction has been used to study the resulting phases present in the cathode after battery discharge.
