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
