Body-panel batteries from Volvo: Carbon fibres, nano structured batteries & super capacitors


Volvo Car Group has developed a concept for lightweight structural energy storage components that could improve the energy usage of future electrified vehicles.

The material, consisting of carbon fibres, nano structured batteries and super capacitors, offers lighter energy storage that requires less space in the car, cost effective structure options and is eco-friendly.

The EU-funded research project, including nine other major participants, identified a feasible solution to the heavy weight, large size and high costs associated with the batteries seen in hybrids and electric cars today, whilst maintaining the efficient capacity of power and performance. The research project took place over 3.5 years and is now realised in the form of car panels within a Volvo S80 experimental car.

The breakthrough

The answer was found in the combination of carbon fibres and a polymer resin, creating a very advanced nanomaterial, and structural super capacitors. The reinforced carbon fibres sandwich the new battery and are moulded and formed to fit around the car’s frame, such as the door panels, the boot lid and wheel bowl, substantially saving on space. The carbon fibre laminate is first layered, shaped and then cured in an oven to set and (more…)
