Three-in-One Device Stores Energy, Makes Hydrogen

UCLA researchers Richard Kaner and Maher El-Kady, “Have designed a device that can use solar energy to inexpensively and efficiently create and store energy, which could be used to power electronic devices, and to create hydrogen fuel for eco-friendly cars.”  Kaner and El-Kady have devised many low-budget approaches to capturing and exploiting energy, such as their method of “burning” supercapacitors on a personal computer DVD.  Their newest accomplishment, according to Kaner, “Could dramatically lower the cost of hydrogen cars.” It would be useful in urban or rural areas, or even on remote battlefields, giving users the ability to make both electricity and fuel from the same device. In cities, it could store surplus energy from electrical grids, and in more …

Graphene Supercapacitor Shows Promise and Longevity

A forever battery would be nice, wouldn’t it?  Something low cost that could be recharged in seconds, time after time, indefinitely, and be about as environmentally sensitive as Greenpeace and the Sierra Club combined – there’s the ideal battery. That might seem like a miracle, and it relies on that miracle material – graphene – for its many astounding properties to help make this flexible battery a reality. Dr. Han Lin of Swinburne University in New South Wales, Australia has 3D printed his prototype battery at a much lower cost than with previous production techniques.  The immediate “take” on this material is that it could be used in things like watch straps, powering the attached timekeeper, or in (inter)active sports …

Kaner and El-Kady Explore New Areas of Energy Storage

Now here’s a mission statement.  “Engineering three-dimensional hybrid supercapacitors and microsupercapacitors for high-performance integrated energy storage.” Conventional wisdom says that super and ultracapacitors don’t have the energy storage of batteries, and even given their outstanding ability to deliver power at high levels pretty much instantly, will never be able to run an electric vehicle for extended periods.   So many researchers, with the notable exception of Dr. Richard Kaner and graduate student Maher El-Kady at UCLA have turned their attention to batteries, and not capacitors. They recognize that electronic devices have improved immensely over the past decades, but “the slow pace of battery development has held back technological progress.” Looking to synthesize rather than differentiate, the two California NanoSystems Institute researchers …

What Do You Have on Your DVD Burner?

Richard Kaner and Maher El-Kady have “micro-scale graphene-based supercapacitors” on their front DVD burner, showing an energetic alternative to saving all those ‘80’s rockers to disc. Dr. Kaner is a member of the California NanoSystems Institute at the University of California at Los Angeles (UCLA) and professor of chemistry and biochemistry.  He and graduate student El-Kady are using a “consumer grade” LightScribe DVD burner to make dozens of micro supercapacitors on what looks like a typical DVD. Dr. Kaner’s research lab hosts 17 undergraduate and graduate student researchers who’ve helped amass at least 390 papers in four main areas of research; conducting polymers, graphene, superhard materials and thermoelectric materials.  Their recent investigation of supercapacitor fabrication seems to encompass almost all …
