We present a temperature- and polarization-resolved phononic and electronicRaman scattering study in combination with the first-principles calculations onthe kagome metal Ni$_3$In with anisotropic transport properties and non-Fermiliquid behavior. At temperatures below 50 K and down to 2 K, several Ramanphonon modes, including particularly an interlayer shear mode, exhibitappreciable frequency and linewidth renormalization, reminiscent of the onsetof the Kondo screening without an accompanying structural or magnetic phasetransition. In addition, a low-energy electronic continuum observed inpolarization perpendicular to the kagome planes reveals strong temperaturedependence below 50 K, implying thermal depletion of incoherent quasiparticles,while the in-plane continuum remains invariant. These concomitant electronicand phononic Raman signatures suggest that Ni$_3$In undergoes an anisotropicelectronic crossover from an incoherent to a coherent Kondo lattice regimebelow 50 K. We discuss the origin of the anisotropic incoherent-coherentcrossover in association with the possible anisotropic Kondo hybridizationinvolving localized Ni-$3d_{xz}$ flat-band electrons.
