Web2 dagen geleden · First, PEO with high donor numbers can produce strong Li + coordination, which is conducive to the solvation of Li +, but at the cost of weakening the mobility of Li +. [ 10 , 11 ] Secondly, the relatively low dielectric constant of PEO makes the anion interact less with the PEO matrix, so the mobility of the anion is much higher than … Web8 apr. 2024 · Ions transport in an aqueous electrolyte can be modelled using Nernst-Planck equation, which includes three terms of diffusion, migration and convection. It seems that …
