The superconductivity and structural properties of lithium under high pressure are investigated by simultaneous measurements of X-ray diffraction and electrical resistance at low temperature below 25 K. The structural transitions fcc - hR 1 - cI 16 near 40 GPa and the possible structural transition to higher pressure phases were observed above 70 GPa. The superconducting transition temperature T c increases with applied pressure and has maximum in fcc phase. At higher pressures, T c decreases in hR 1 phase and increases again in cI 16 phase. We did not observe T c above 9 K for pressures above 70 GPa. Superconductivity possibly disappears in high pressure phases above 70 GPa.
