Hmm... huge power density. They don't say that yet but I wonder if some production defects or just aging may cause some internal energy "leaks" which may end up with an explosion. A bit like a dynamite ... (or lithium batteries).
We don't reference the scholarly papers that give all the details, because those publishers charge you. However, the online free abstract gives the following details: from exfoliated graphite oxide the team synthesized a porous carbon with a surface area of up to 3100 square meters per gram. Two-electrode supercapacitor cells were constructed yielding high gravimetric capacitance and energy density with organic and ionic liquid electrolytes. The processes used to make this carbon are readily scalable to industrial levels." http://bit.ly/mc0eS7
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
