Abstract:
1. A half-cell comprising: an electrode formed of a current collector containing one or more transition metals from groups 4 to 12 of the Period Table of the Elements, and of an electrochemically active material present on the surface of the current collector in the form of a nanostructured conversion film containing nanoparticles having an average diameter of between 1 nm and 1000 nm, said electrochemically active material containing at least one compound of the transition metal or the transition metals present in the current collector; and a 1 μm to 50 μm thick, water- and air-impermeable lithium-ion conductive, solid electrolyte deposited on the nanostructured conversion film in a plurality of mutually adjacent regions separated by gaps that are not covered by the electrolyte filled with a water- and air-impermeable material that is more deformable, plastically or elastically, than the lithium-ion conductive, solid electrolyte, the lithium-ion conductive, solid electrolyte being a ceramic.
