Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Pyrometallurgy, which traditionally doesn’t recover carbon or lithium, seems likely to be phased out. Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. They need to contain them.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

The best-known wearable energy-harvesting tech today is, of course, solar, which pulls down electrons from sunlight or ambient light. But solar is just the opening gambit. A backpack with a giant solar panel might work technically, but not in reality. Leveraging watch tech for…bisons? Batteries die before animals do.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

Research on thermochemical water splitting cycles largely began in the 1960s and 1970s and involved nuclear reactors and solar collectors as the energy sources, the team notes in their paper. Because of the requirement of high-temperature heat sources, these types of cycles have been investigated for use with solar concentrators.

Vanderbilt/ORNL team discovers new form of crystalline order that could be attractive for thermoelectric applications

Green Car Congress

Writing in the journal Nature Communications , the researchers reported finding this unusual arrangement of atoms while studying nanoparticles made from the semiconductor copper-indium sulfide (CIS), which is being actively studied for use in solar cells. Materials Thermoelectrics Waste Heat Recovery' CIS is a bit more complicated.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

However, lithium is sourced almost exclusively from other countries, either concentrated using a solar evaporation process from natural brine sources or recovered from ore. It is essential for the manufacturing of lithium-ion batteries commonly used for everything from electric vehicles to cell phones and laptops.
