In-situ diffraction study of electrochemical intercalation of potassium solvated by tetrahydrofuran into graphite. Observation of a fractional stage n = 4/3
Ternary graphite intercalation compounds, TGIC, with potassium and tetrahydrofuran (THF) can be obtained by two main synthesis methods: (i) by direct preparation from graphite plunged into a molar solution of a highly reducing agent as potassium naphtalenide into THF1, and (ii) by ternarisation of a binary graphite intercalation compound, BGIC, plunged in liquid THF2,3 or in a vapour-bath of THF with a vapour pressure of some Torrs4,5.
