This invention provides a novel solution to form an artificial interphase on the electrode to protect it from fast declining electrochemical behaviors, by depositing Doped-Metai Oxides Layer, by ALD or CVD. Metals discussed here are IVA-VIA elements (Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W) and dopants includes here B, Al, C, Si, N, P, S, allowing the oxide network to be porous, which may be favored by the presence of the dopant. The film also needs to be thin, possibly discontinuous, and lithium ion conductive enough, so that the addition of this thin film interface allows fast lithium ion transfer at the interface between electrode and electrolyte.

The invention relates to a process for preparing methanol, in which a synthesis gas comprising carbon oxides and hydrogen is provided, which is passed at elevated pressure and elevated temperature through a catalyst bed of a methanol synthesis catalyst for conversion of the synthesis gas to methanol to obtain a product stream comprising crude methanol and un reacted synthesis gas, and the product stream is cooled for condensation and removal of crude methanol comprising at least methanol and water. Un reacted synthesis gas is recycled to the catalyst bed inlet and combined with the synthesis gas, resulting in a mixed synthesis gas which is passed through the catalyst bed at elevated pressure and elevated temperature. It is envisaged in accordance with the invention that the mixed synthesis gas at the catalyst bed inlet has a stoichiometry number SN of ? 0.80, the catalyst bed in the conversion of the mixed synthesis gas to methanol has a maximum catalyst bed temperature of ? 280°C, and the mixed synthesis gas at the catalyst bed inlet has a carbon monoxide concentration of ? 20% by volume. The combination of these parameters effectively suppresses the formation of by-products.
