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.
