An optical element is provided. The optical element may comprise a material, the material being a matrix and a set of particles included in the matrix, the material having a molar fraction of SiOhigher than or equal to 65 percent, each particle having a dimension smaller than or equal to 80 nanometers.

Optical element and associated manufacturing method

The present invention relates to a method for preparing a completely solid Li-ion battery having a solid state body wherein the battery is assembled in a single step by stacking at least one layer of a powder mix including a positive electrode active material and a solid electrolyte, at least one intermediate layer of a solid electrolyte and at least one layer of a powder mix including a negative electrode active material and a solid electrolyte, and simultaneous sintering of the three layers at a pressure of at least 20 MPa, under pulsating current. The invention also relates to the Li-ion battery obtained by such a method.
