Introduction
The technology, designed to improve the utility and efficiency of future electric vehicles (EVs)
GOOD IS NOT ENOUGH GOOD
The heavier the vehicle is, the more energy it needs to get moving
Weight of batteries can be a large fraction of the overall weight
Batteries do not contribute to load carrying capability
Innovation• Achieve a three-dimensional interpenetrating
network of anode and cathode materials .
• Alternative structural battery concept based on fiber-reinforced network for increasing strength while maintaining the energy storage capabilities of Li-ion battery system
carbon fibres battery Anode: C-fibre
Counter: Lithium metal foil
Most common binder is PVDF (Polyvinylidene Fluoride)
Voltage profiles of carbon electrodes
Development phase to final product
Projected Benefits of Structural Weight Reduction
Baseline 15 yr projection
30 yr projection
Structural weight reduction
25% 50%
Power density
3hp/lb 4hp/lb 6hp/lb
