Kinetics and thermodynamics of the Li/Li+ couple in tetrahydrofuran at low temperatures (195-295 K)

Journal article

Kinetic and thermodynamic (formal potential) data relating to the synthetically useful Li/Li+ couple in tetrahydrofuran (THF) solvent at a range of temperatures (196-295 K) are reported. Formal potentials, E f0 have been measured versus the standard reference electrode, Fc(4mM)/Fc+PF6- (4mM)) in THF. At 295 K the following data have been obtained using a mathematical model to simulate the electro-deposition (metal deposition and growth kinetics) processes of lithium (Li) on a platinum microelectrode; a Ef0 of -3.48 ±0.005 V, dEf0/dT = -9.2 (±0.5) x 10-4VK-1, the standard electrochemical rate constant, k0=1 (± 0.1) × 10-4cms-1, transfer coefficient, α = 0.57 ±0.03 and diffusion coefficient, D = 8.7 ±0.1 × 10-6 cm2 s-1.
