Hemiammine lithium borohydride, LiBH·1/2NH, is characterized and a new Li conductivity mechanism is identified. It exhibits a Li conductivity of 7 × 10 S cm at 40 °C in the solid state and 3.0 × 10 S cm at 55 °C after melting. The molten state of LiBH·1/2NH has a high viscosity and can be mechanically stabilized in nano-composites with inert metal oxides and other hydrides making it a promising battery electrolyte.
半氨合硼氢化锂（LiBH₃·1/2NH₃）得到了表征，并确定了一种新的锂传导机制。它在40℃固态下的锂电导率为7×10⁻⁵ S/cm，熔化后在55℃时为3.0×10⁻³ S/cm。LiBH₃·1/2NH₃的熔融态具有高粘度，并且在与惰性金属氧化物和其他氢化物形成的纳米复合材料中可实现机械稳定，这使其成为一种有前景的电池电解质。
