| Abstract: | 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,  have been measured versus the standard reference electrode,  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  of ?3.48 ± 0.005 V,  = ?9.2 (±0.5) × 10?4 V K?1, the standard electrochemical rate constant, k0 = 1 (± 0.1) × 10?4 cm s?1, transfer coefficient, α = 0.57 ± 0.03 and diffusion coefficient, D = 8.7 ± 0.1 × 10?6 cm2 s?1.
