Zu ̈ ttel,, Journal of Physics: Conference Series 340 (2012) Ref.: Friedrichs, O; Kim, JW; Remhof, A; Wallacher, D; Hoser, A; Cho, YW; Oh, KH; Zuttel, A, Physical Chemistry Chemical Physics 12:18 (2010), pp Towards room temperature, direct, solvent free synthesis of tetraborohydrides, e.g. LiBH4 Due to their high hydrogen content, tetraborohydrides are discussed as potential synthetic energy carriers. On the example of lithium borohydride LiBH 4, we discuss current approaches of direct, solvent free synthesis based on gas solid reactions of the elements or binary hydrides and/or borides with gaseous H 2 or B 2 H 6. The direct synthesis from the elements requires high temperature and high pressure (700°C, 150bar D 2 ). Using LiB or AlB 2 as boron source reduces the required temperature by more than 300 K.
