– Binder Volume reduced by a factor 2 at least. – Value for Customer : With 2% of binder reduction gives 2% more capacity : 2% of 250$/kWh = 5$/kWh of gain. – If reduce binder concentration factor 2 and 2X price cost is still 2$/kWh. Adhesion on electrode vs binder type and concentration

Binders contribute to cost reduction
through innovation.
- Strategy of Solvay development Increasing adhesion for reducing binder content : • Generation #3 binder (Solef 5130) reduce binder concentration at least by factor 2
Looking for cost reduction 30 $/kWh. (around 10%).
represent less than 2 $/kWh.
• A price reduction of 10% would contribute only by less than 1% of the objective
