Abstract: A solid-state battery (20) with a solid electrolyte (8) and to the method for producing same. The method includes: protonating a body (11) containing, preferably being entirely made of, a protonatable ceramic material, to form a protonated layer (12, 13) on the body (11); depositing a metal element forming an anode (14) on the protonated layer (13) on a first side (7) of the body (11); assembling a cathode (15) on a second side (9) of the body (11), preferably opposite the first side (7) of the anode (14); and forming dendrites (18) from the metal element in the protonated layer (13) of the body (11).

The method includes: protonating a body (11) made of, a protonatable ceramic material, to form a protonated layer (12, 13) on the body (11); deprotonating the protonated layer (13) to obtain a porous layer provided with mini-cavities (18); depositing a metal element forming an anode (14) on the deprotonated layer (13) on a first side (7) of the body (11), and infiltrating mini-cavities (18) of the porous layer by the metal element, and assembling a cathode (15) on a second side (9) of the body (11), preferably opposite the first side (7) of the anode (14).

Abstract: A polycrystalline ceramic solely formed based on alumina, on chromium oxide and on magnesium oxide, where the polycrystalline ceramic contains between 0.8% and 1.2% of chromium oxide by total weight of the polycrystalline ceramic and between 0.03% and 0.09% of magnesium oxide by total weight of the polycrystalline ceramic, making it possible to obtain a red ceramic with a toughness (Kc) at least equal to 2.8 MPa·m1/2.
