Researchers in China report using air oxidation–water leaching to recover lithium selectively from spent LiFePO 4 (LFP) material, in which the high leaching efficiency of lithium and the good separation effect of lithium and iron were achieved simultaneously. An open-access paper on their work is published in the RSC journal Green Chemistry.

Example of micro fibers produced with 20 wt % AB (ammonia borane) in water as core solution, showing smooth (nonporous) and cylindrical (noncollapsed) fibers; from a 2010 paper by the scientific team. The material could allow hydrogen to be stored in a cheap and practical way for transport applications, the company says.

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.

Even on land, getting oil from tar sands depletes water and other resources and doubles oil’s carbon footprint. And oil only seems cheap. We’ve already decided we’re going to fix already-built houses, offices and factories that waste energy. But let’s realize: defending our nation is never cheap.

Then came the rapid ascent of production in China and with it a flood of low-cost magnesium. The source of magnesium can be from sea water, brine, dolomite, magnesite, and carnallite. In the 1990s, the magnesium metal market was dominated by supply from North America (46%), what is now the CIS (25%) and western Europe (19%).
