Description:
<jats:title>Abstract</jats:title><jats:p>Single phase samples of lithium‐doped β‐rhombohedral boron were synthesised by different high temperature routes.Both single crystals and crystalline powders were obtained. Characterisation was done by electron energy loss spectroscopy, energy‐dispersive X‐ray spectroscopy and X‐ray diffraction. According to the crystal structure determination based on single crystal and powder data, the phase investigated is LiB<jats:sub>∼10</jats:sub>. Depending on the synthesis route, LiB<jats:sub>∼10</jats:sub> was found to form a compound with composition Li<jats:sub>30</jats:sub>B<jats:sub>309</jats:sub>. Further lithium intercalation is possible.</jats:p>
