Özet

The formation of dendrites is a critical drawback for the utilization of lithium in secondary batteries. These amorphous crystals can pierce into the polymer electrolyte and short the cell. Therefore the design/selection criterion requires the mechanical compatibility of the grown dendrites from electrode and the solid polymer electrolyte. Hereby we grow the morphology of lithium. We compute the porosity and consequently, we perform force field calculations to extract its effective bulk modulus. We show that despite extremely high porosity, the dendrite bulk modulus yet remains significant.
