The big story for nanotechnology in lithium-ion (Li-ion) batteries in the past year has been the demise of high-flying nanotech startups A123 Systemsand Ener1. Both of these companies had developed nanotech-based solutions for improving the Li-ion battery and both companies announced bankruptcies in the past year after having received millions of dollars in capital investment. That’s why much of the news of late surrounding nanotechnology and the Li-ion battery has been of the R&D variety.

In that vein, research into usinggraphene hybrids to replace graphite in Li-ion electrodes seems to have increased in the past year and there have been some significant breakthroughs to improve both manufacturability and performance. But there have also been somecommercial ventures in the past year that have licensed some of that research to make a go of using graphene in Li-ion batteries.
