Vanderbilt University researchers are imagining a future in which our electrical gadgets are no longer limited by plugs and external power sources. The intriguing prospect is one of the reasons for the current interest in building the capacity to store electrical energy directly into a wide range of products, such as a laptop computer casing [...]

Scientists at Oregon State University (OSU) have discovered a fundamental chemical action that could allow cellulose to soon play a major role in making high-tech energy storage devices.  The method discovered turns cellulose, the most abundant organic polymer on Earth and a key component of trees, into an important building block for supercapacitors. OSU chemists [...]

Research engineers at the Illinois Sustainable Technology Center at the University of Illinois (UI) find wood biochar supercapacitors can produce as much power as today’s activated-carbon supercapacitors at a fraction of the cost.  The report noted that the wood bio-char would be sourced from forest products waste, an environmentally friendly source to make power storage. [...]

A research team led by Professor Dan Li of the Department of Materials Engineering at Monash University in Australia has developed a completely new strategy to engineer graphene-based supercapacitors.  The Monash University researchers have brought next generation energy storage closer with an engineering first – a graphene-based device that is compact, yet lasts as long [...]

Ionova Technologies, Inc. reports that its zinc-ion-based ZIP-Cap asymmetric ultracapacitor is expected to provide a huge improvement in ultracapacitor design.  Tracking into the two notorious problems of cost and density Ionova has announced a 25-fold improvement in build costs and a 5-fold improvement in energy density.  These are major improvements, especially for consumers building power [...]
