Study links carbon fiber microstructure to Li insertion mechanism in structural batteries

Green Car Congress

Carbon fibers have already beeen demonstrated as high-capacity Li-ion battery anodes, opening the way for their use as structural electrodes—i.e., simultaneously carrying mechanical load and storing electrical energy. The researchers studied the microstructure of different types of commercially available carbon fibers.

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 million (US$4.7-million)

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. For capacitors, voltage translates to electrons stored —the voltage drop across a capacitor is proportional to its total charge.) volts for about 60 hours.
