摘要:
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.
摘要:
The invention relates to a process for producing a thermogenerator (10) comprising a plurality of thermocouples formed of p-type thermoelements (12) and n-type thermoelements (14). A wafer (18), provided with a plurality of holes (20a, 20b) is covered in thermoelectric material powder (22, 24). Pressure (P) is applied to the powder (22, 24) so that it penetrates into the holes (20a, 20b) while heating so as to form a plurality of p-type and n-type thermoelements (12, 14) contained in the wafer (18). The wafer (18) is thinned, the thinned wafer thus forming a matrix (16) in which the thermoelements (12, 14) are contained. While preserving the matrix (16) the p-type thermoelements are connected so as to form thermocouples and the n-type thermoelements are connected so as to form thermocouples, thereby obtaining a thermogenerator (10).
