Solid-state synthesis simplifies cathode manufacture

The production and processing of cathode active materials (CAM) are among the largest contributors to the cost of lithium-ion battery manufacturing. Typical CAM manufacture involves multiple, multi-phase steps in a co-precipitation process that requires a large amount of water and…

Recovering lithium with thermal-swing liquid-liquid deionization

Much of the planet’s lithium is contained in brine, but the concentration is often quite low, making it difficult to efficiently extract lithium — typical extraction technologies may only demonstrate 30–60% yield. Adionics (Les Ulis, France; www.adionics.com) has developed a…

This process makes freshwater from brine while capturing CO2

A new electrochemical technology for direct-air capture (DAC) of atmospheric CO2 can also produce freshwater from brackish water or brine waste from desalination or wastewater treatment facilities (diagram). The technology, developed by Capture6 (Berkeley, Calif.; www.capture6.org), splits the salt content…
