Boron-hydrogen compounds are of increasing importance as electrolytes in solid state batteries, for hydrogen storage and possibly as high temperature super conductors. Solvent based methods are of increasing importance to obtain pure products, for purification of materials and also for the synthesis of novel compounds. In this context, the solubility information of several classes of metal-boron-hydrogen compounds such as borohydrides, -decahydridodecaborates, -dodecahydridododecaborates, - and -hydridoborates in typical solvents is vital.

Thermal batteries are systems that store heat made from various energy sources, and can be used to produce electricity upon demand. These systems are easily scalable and can be installed in cities, homes and remote locations.

However, to date only a fraction of these compounds has been investigated as solid-state electrolytes. Here, MBHNH (M = Li and Na) hydroborates are synthesized and investigated as electrolyte materials for all-solid-state batteries.

A review of the synthesis, as well as a thorough characterization using H NMR, B NMR, C{H} NMR, FTIR, XRD, XRD, DSC-TGA, RGA-MS, TPPA, and EIS has newly identified polymorphic phase changes for Na[B(OMe)], K[B(OMe)], Li[B(OMe)], Na[B(OEt)], Na[B(OBu)], and Na[B(OBu)]. The crystal structure of K[B(OMe)] was also solved in 41/ ( = 22.

For the production of NaH from NaOH, a variety of metallic reducing agents (Mg, Al, Si, CaH, Cr, Mn, and Sr) were investigated. The reactions took place in an autoclave reactor with paraffin oil at 250 °C and 14 bar of H pressure.
