Abstract
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.
