Li4SiO4 belongs to the so-called tetrahedral LISICON family of ionic conductors, heavily investigated in the 80's by A.R. West and co-workers. We reported in 1995 that doping Li4SiO4 with Aluminum (or Boron) results in significant improvement of the ionic conductivity, to reach values up to 10-2 S.cm-1 at 300°C for Li4.3Al0.3Si0.7O4 [6-7].
