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)

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.
