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

Green Car Congress

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.

I knew I wanted something for her that was cheap to maintain, had a reliable automatic transmission, came with cruise control, AC. The cost of that usually starting just below $1,000 or changing the faulty modules (28 modules in a pack) individually that is much cheaper. Sometimes the engine water pump might leak.

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

I live in Manitoba , a province of Canada where all but a tiny fraction of electricity is generated from the potential energy of water. There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Construction of large dams began before World War II.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

Their journey began with a question posed by its founders, Tommi Eronen and Markku Ylönen, when they were university classmates: “Is it possible to build an energy-self-sufficient and cost-effective hippie commune for engineers using only solar power?” There is only so much heat you can add to water before it becomes steam,” says Eronen.
