Virginia Tech team demonstrates green manufacturing method for Li-ion batteries

Green Car Congress

The researchers found that the electrodes fabricated via water-based processing demonstrate comparable rate performance and cycle life to the ones from conventional solvent based processing. Given that the global lithium-ion battery production capability is ~400 GWh, humongous amount of NMP is needed. —Li et al.

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. Next, the nanotubes were put into an emulsion of oil and water. The coated carbon nanotubes condense into spheres when the water evaporates. —Xiaolin Li.
