Designing electrode architectures to facilitate electrolyte infiltration for lithium-ion batteries

The electrolyte infiltration is a critical step in the Lithium-ion battery (LIB) cell manufacturing process, impacting for instance solid interphase heterogeneity and ageing. rate effectivity are tied to porous mesostructure dimensions of electrodes separator, which mainly dictated by electrochemical performance requirements. We propose here use architectures with layers varying pore network properties as potential approach tune wettability sandwich. perform simulations based on Lattice Boltzmann Method analyse saturation function time. This descriptor can be used evaluate different options architectures. identify porosity, porosity distribution, particle size distribution active material main experimental variables that allow influencing process full cells an advantageous way. Our modelling framework allows recommendation blueprints reduce time energy invested this LIB manufacturing.
