Infiltrated porous oxide monoliths as high lithium transference number electrolytes

We show for the first time that liquid-solid lithium electrolytes can exhibit both a very high lithium transference number (up to 0.89) and high overall ionic conductivity (up to 0.48 mS cm(-1)) when the solid contains a large number of mesopores covered by a high density of -OH groups enabling anionic adsorption.
