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.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

Researchers synthesize battery cathode from lignin derivatives

Green Car Congress

Grzegorz Milczarek from Poznan University of Technology (Poland), and Olle Inganäs from Linköping University (Sweden), have combined lignin derivatives, which are electronic insulators, with polypyrole, a conductive polymer, into an interpenetrating composite suitable for use as a battery cathode. 1 (inner to outer).

Biogas Climate Benefit Greater Than Previously Thought

Green Car Congress

A research group at the Lund University Faculty of Engineering calculated the figures on behalf of the Swedish Energy Agency after having analysed a biogas plant in Skåne. In Sweden there are some 20 similar plants, producing biogas for use in cars and other vehicles. More than 23,000 vehicles in Sweden drive on biogas.

Copenhagen Diagnosis Released, Detailing Accelerating Indicators of Climate Change In Last Three Years

Green Car Congress

Global carbon dioxide emissions from fossil fuels in 2008 were nearly 40% higher in 2008 than in 1990. The degradation of natural carbon sinks amplifies the effects of climate change, producing the same net effect on atmospheric concentrations of GHGs as increases in greenhouse gas emissions. project business as usual emissions.

Researchers engineer first low-methane-emission, high-starch rice; benefits for GHG control, food and bioenergy

Green Car Congress

Now, however, with the addition of a single gene from barley (SUSIBA2), a team of researchers in China, Sweden and the US has engineered a strain of rice—now named SUSIBA2—that can be cultivated to emit virtually no methane from its paddies during growth.
