It happens to all of us: it’s the middle of the afternoon and you’re checking your smartphone for your latest messages and emails, but that red icon at the top of your phone’s display appears, warning you that your battery life is low. More than likely, your phone will die before making it through the rest of the day. But imagine if you didn’t have to worry about any that? What if your smartphone or other electronic devices could be charged in just a few seconds? And what if those devices used a power supply that's biodegradable and safe for the environment? The magic is in the idea of a supercapacitor. In this talk, I’ll present the efforts we have undertaken in the Kaner Lab to develop a high-performance graphene supercapacitor—we coined “the super supercapacitor”. We produced smaller versions of these devices, called micro-supercapacitors, that can be integrated directly on-chip to provide the power for future electronics. Strategies to further boost the capacity of the super supercapacitor will be covered. I’ll also highlight our efforts over the past year for scaling up this technology to the industrial level.
