Abstract
The invention relates to a method for fabricating an electrode which includes coating of an aqueous ink over the whole or part of a current collector followed by drying of said ink. The aqueous ink is produced by acidification of an aqueous dispersion including an electrochemically active material having a titanium and lithium oxide base until a pH value comprised between 9.0±0.1 and 10.0±0.1 is obtained. The invention also relates to an aqueous ink for an electrode including an electrochemically active material having a titanium and lithium oxide base and having a pH between 9.0±0.1 and 10.0±0.1, preferably equal to 10±0.1.
