Cable-type battery and method for fabricating a cable-type battery

A method for fabricating a cable-type battery comprising the following successive steps:

• providing at least a first strand of a first polarity type, and at least a second strand of a second polarity type, the second polarity type being the opposite of the first polarity type,
• arranging the first strand and the second strand in a sheath or electrolyte layer, the electrolyte layer being ionically conducting and electrically insulating, the first strand being ionically connected to the second strand,
• a method wherein the first strand is coated by at least one spacer, the spacer being electrically insulating, the spacer being configured to prevent any direct contact between the first strand and the second strand,
• and wherein the spacer is formed by a first material having a mechanical resistance greater than a mechanical resistance of a second material forming the electrolyte layer.
