    摘要: The invention relates to a process for manufacturing a silicon-based electrode and to a silicon-based electrode. It also relates to a lithium battery comprising such an electrode. The process of the invention consists in fabricating a silicon-based electrode of the type that includes a step of electrochemically depositing silicon on a substrate by cyclic voltammetry in a solution comprising at least one ionic liquid and a silicon precursor of formula SinX2n+2, in which x is Cl, Br or I and n is equal to 1 or 2. The electrode of the invention is particularly applicable in the lithium battery field.

    摘要: A bipolar battery including unit cells fitted with an element including a first electronic conductive support, a second electronic conductive support, an electronic conductive connection connecting the first and the second support, with each support including a first and a second face separate from the first and second faces of the other support, a positive electrode material deposited on one of the faces of the first conductor, and a negative electrode material deposited on one of the faces of the other support. The positive electrode material is supported by the first support, and is positioned facing a negative electrode material, the negative electrode material is supported by the second support, and is positioned opposite a positive electrode material, where the facing electrode materials are separated by an insulator containing an electrolyte, thus forming two juxtaposed unit cells.
