RPI team develops method to use paper-making by-product in lithium-sulfur batteries

Green Car Congress

Lignosulfonate, a sulfonated carbon waste material, is a major by-product in the papermaking industry. Researchers at Rensselaer Polytechnic Institute (RPI) have now developed a method to use this cheap and abundant waste byproduct to build a components for lithium-sulfur batteries. Click to enlarge.

Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

The use of LFP batteries in EVs is increasing rapidly, especially in China, due to low-cost, safety, excellent thermal stability and superior cycling performance. As the most cheap and green oxidant, air may be suitable as the oxidant to selectively extract lithium from the LFP cathode material in the water leaching process.

Material Derived From Carbonized Chicken Feathers Could Meet DOE Hydrogen Storage Targets

Green Car Congress

Scientists at the University of Delaware are developing a new low-cost material for hydrogen storage—carbonized chicken feathers (CCFF)—that they say could meet the DOE requirements for hydrogen storage and are competitive with carbon nanotubes and metal hydrates at a tiny fraction of their cost.

Delivery of renewable isooctane to Audi tips interesting potential non-biomass pathway for biogasoline; “e-benzin” as solar fuel

Green Car Congress

However, following the delivery of the first renewable isooctane, Reiner Mangold, Audi’s head of sustainable product development, said that Audi was “ now looking forward to working together with Global Bioenergies on a technology allowing the production of renewable isooctane not derived from biomass sources ”—i.e.,
