Enert of materials and binders b) Optimization of the benefit of a material replacement ?
3. Technical impact of a binder replacement. 4. Cost impact of material replacement.
– 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
• Five Li-ion cell suppliers account for 88% of plug-in vehicle market, led by Panasonic • Beyond the top five, more than 20 other cell makers fight for the remaining 12% in market share

Big LIB leaders today regarding automotive, and cost if key
• New materials can only be implemented in new projects for growing segments
• CAGR (2020-2015) of automotive 25-30% while for consumers around 10%.

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

- Even a unrealistic price reduction of 50% would
reach only 3% of the target.
• Binder Price can hardly contribute to have a
significant impact at battery level.
