ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

These plants pump hot water from geothermal deposits and use it to generate electricity. The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium.

Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate. The group fabricated their device using CFRP, sodium potassium niobate (KNN) nanoparticles, and epoxy resin. volts for about 60 hours. They said, ‘We don’t know.
