Le mélange à base de lignine qui est approprié pour le côté négatif est obtenu par une réaction de lignosulfonates dans un autoclave hydrothermique à des températures et une pression élevées sur la pression atmosphérique. Un avantage est que le matériau de départ pour la fabrication des électrolytes de RFB est très peu coûteux et respectueux de l'environnement. Le mélange peut être fabriqué en une seule étape sans étapes de réaction supplémentaires et peut être utilisé directement sans amélioration supplémentaire.
