Researchers at North Carolina State University have created a new flexible nano-scaffold for rechargeable lithium-ion (Li-ion) batteries that could help make cell phone and electric car batteries last longer.

The research, published online in Advanced Materials, shows the potential of manufactured sheets of aligned carbon nanotubes coated with silicon, a material with a much higher energy storage capacity than the graphite composites typically used.
