The micro-architectured, ultra-lightweight supercapacitor material is able to retain energy on par with those made with electrodes 10 to 100 times thinner.

For the first time ever, scientists at Lawrence Livermore National Laboratory and UC Santa Cruz have successfully 3D-printed supercapacitors using an ultra-lightweight graphene aerogel, opening the door to novel, unconstrained designs of highly efficient energy storage systems for smartphones, wearables, implantable devices, electric cars and wireless sensors.

Using a 3D-printing process called direct-ink writing and a graphene-oxide composite ink designed at the Lab, the LLNL team was able to print micro-architected electrodes and build supercapacitors able to retain energy on par with those made with electrodes 10 to 100 times thinner.
