Aqua Metals produces high-purity LiOH directly from recycled lithium-ion batteries

Green Car Congress

Aqua Metals has recovered high-purity lithium hydroxide (LiOH) from lithium-ion battery black mass at the company’s Li AquaRefining recycling facility located at the Tahoe-Reno Industrial Center (TRIC). Aqua Metals in January electroplated its first critical battery metal—copper—from Li-ion black mass.

PNNL team develops carbon nanotube-silicon microspheres as high-performance Li-ion anodes

Green Car Congress

Silicon is an appealing anode material for Li-ion batteries because it can hold about 10 times the electrical charge per gram compared to graphite. Here we design and synthesize hierarchical carbon-nanotube@silicon@carbon microspheres with both high porosity and extraordinary mechanical strength (>200?MPa)
