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.

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.

They used nickel and aluminium as materials for the cathode and anode respectively, with sodium aluminium tetrachloride (NaAlCl 4 ) as the molten-salt electrolyte—all relatively cheap, earth-abundant materials. This electrolyte has a melting point of around 157ºC, and remains solid over a large spectrum of room temperatures. “We

The method can be applied to other electrode materials, too, making energy-dense, low-cost battery materials a realistic possibility. There are huge challenges associated with using low-cost,micrometre-sized Si source materials. —Yi Cui. Here we introduce a method to encapsulate Si microparticles (∼1–3 µm).

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.

One of the benefits of using print electronics is being able to mass-produce at a low cost, says Gregory Whiting at the University of Colorado, Boulder, one of the principal investigators of the team working on the sensors. One problem with mass-producing sensors, however, is that it creates a lot of waste.

Most of the methods currently under development involve converting biomass or waste, while there are also approaches to directly produce liquid transportation fuels from sunlight and carbon dioxide, typically using photosynthesis. Batteries for Electrical Energy Storage in Transportation (BEEST).
