dc.description.abstract	Abstract In this work, we use the quasiclassical theory of superconductivity to calculate the electronic contribution to thermal conductivity of Ni doped Bi4O4S3 in its normal and superconducting state. The theory is formulated for low temperature when heat transport is limited by electron scattering from random defects and for superconductors with nodes in the order parameter. We use recent results on the Boltzmann equation, heat current density, total electron energy in k-space and electronic heat capacity to determine the electronic thermal conductivity of Ni doped Bi4O4S3 . The expression for electronic thermal conductivity,κel at superconducting and normal states have been determined and plotted as a function of temperature(T). The phase diagrams show the linear dependency of electronic thermal conductivity,κel of Ni doped Bi4O4S3 with temperature in normal state and have a kink in the superconducting state. Key words: Boltzmann transport equation, superconductivity, Ni doped Bi4O4S3, thermal conductivity.	en_US
