Definitions
- the present invention relates to a new process for the preparation of electrochemical electrodes and to the electrodes thus obtained.
- the process allows the preparation of electrodes partially or entirely covered by a film obtained by spreading and drying, on the electrode, an aqueous solution comprising a water-soluble binder and an active material.
