Claim 0:
1. A process for obtaining an electrode, comprising:
depositing a composition onto an electrical current collector,
wherein the composition comprises:
at least one solvent comprising:
N-methylpyrrolidone (NMP) in a amount of between 80% and 98.99% by mass, limits inclusive;
water in an amount of less than 1% by mass; and
at least one compound bearing at least one y-butyrolactam or y-butyrolactone ring, NMP excluded, where the at least one compound is present in an amount ranging from 0.01% to 19% by mass, limits inclusive,
wherein the at least one solvent is present in an amount of greater than or equal to 50% by mass relative to the composition, and is obtained by recovering NMP vapors in the presence of air at temperatures above 120° C.;

at least one electron conductor in solid form in an amount of greater than 0 but less than or equal to 50% by mass relative to the composition;
an active filler; and
at least one polymer, and

evaporating off the at least one solvent.
