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
