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…)

Tesla in talks with Samsung SDI for Model X batteries

Tesla in talks with Samsung SDI for Model X batteries

While they deal with some press hype about the recent battery fire in a Model-S, Tesla are also busily trying to find more suppliers for batteries – Samsung SDI and Tesla are in discussions about supplying batters for the upcoming Model X.

Tesla currently use batteries supplied by Panasonic in the Model S. In fact Tesla drives more of Panasonic’s battery revenues in the U.S. than the world’s largest automakers, despite the fact that Panasonic are the also the biggest supplier of batteries for Hybrid vehicles in the US.

As outlined in a recent article about Panasonic’s battery sales upturn: “Tesla’s battery demand now outweighs all other OEMs in the U.S., taking 49% of the market share for battery capacity shipped in the U.S. plug-in and hybrid market in Q2 2013. Others are taking notice of Tesla’s increased clout: Samsung SDI, BYD, and LG Chem have reportedly been in talks with the automaker, seeking to supplement or displace Panasonic. However, they may have to wait for Tesla’s next model, because Tesla could find it difficult to mix cells from different suppliers, due to battery management system considerations, and because the Panasonic-Tesla contract stipulates supplying 80,000 vehicles by 2015.”

Tesla Battery Fire update

Tesla Battery Fire update



Latest update [8th October]: “Tesla Motors had regained most of the value it lost in the wake of the accident” after Jefferies analyst Elaine Kwei boosted her price target on the company’s stock to $210 after visiting Tesla and test driving a Model S.

Key points:

  • Tesla shares fall 6% 24 hours after the news broke
  • Drop is shares may also have been caused by an analyst downgrade
  • Incident report suggested the fire was started in the battery
  • Driver is said to have hit a large piece of metal debris that caused the crash
  • firefighters said to have struggled to contain the flames
  • [8th October]Tesla’s stock value recovers almost to the pre-fire value

Statement from Tesla:

“The vehicle performed as it was designed to do…

…On Tuesday, a Model S collided with a large metallic object in the middle of the road, causing significant damage to the vehicle, the car’s alert system signalled a problem and instructed the driver to pull over safely, which he did. No one was injured, and the sole occupant had sufficient time to exit the vehicle safely and call the authorities.

The fire occurred after one of the 12 batteries used to power the vehicle was ruptured, and ignited. Each of (more…)
