Chalmers team develops structural battery that performs 10x better than previous versions

Green Car Congress

Researchers from Chalmers University of Technology, in collaboration with KTH Royal Institute of Technology in Stockholm, have produced a structural battery that performs ten times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material.

Swedish researchers explore use of carbon fiber as active electrode in structural battery for electric vehicles

Green Car Congress

Woven carbon fiber can act as an electrode for lithium ion batteries. Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car. In this €3.4-million

UCR, Stanford team develops general approach for inexpensive, efficient catalysts for PEM fuel cells

Green Car Congress

In a paper in the journal Small , the team reports that the metal/metal oxide@N-doped graphitic carbon fibers—especially Co 3 O 4 —exhibit comparable ORR catalytic activity but superior stability and methanol tolerance versus the industry-standard platinum in alkaline solutions.

A closer look at Audi’s new R8 e-tron EV and battery

Green Car Congress

The model line-up of the second generation of Audi’s high-performance R8 sports car, unveiled at the Geneva Motor Show earlier this year, includes the new R8 e-tron battery-electric vehicle. Li-ion cell energy density was increased from 84 to 152 Wh/kg; in comparison to the first technology platform, the battery capacity has grown from 48.6

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

And today, technology is maturing to the point that meaningful amounts of these energy giveaways can be harvested to liberate wearables from ever needing a battery. There are, researchers have discovered, a wide range of options to harvest enough microwatts to replace wearables’ batteries. Batteries die before animals do.

Audi provides overview of its 4 distinct EV platforms

Green Car Congress

The high-voltage battery stores up to 95 kWh of energy and can recover up to 30% of energy used to drive the vehicle during regenerative braking applications. Because of this, the e-tron GT is able to charge the battery to 80% in about 20 minutes at a Level 3 DC fast charger with a maximum output of 350 kW.
