Thermodynamic and kinetic limits of Li-ion battery operation
Let us consider battery discharging in two variants: with current I 1 and current I 2 = 2I 1. In the absence of polarization processes (being quasi-reversible processes), the same charge q is necessary to convert electrode materials from the ''charged'' to ''discharged'' state, but in a twice shorter time ( t 1 = 2 t 2 ).
