Hydrothermal synthesis of uniform porous carbon nanospheres and their gas storage capacity

Lee M.K., Nam S.W., Han J.S., Kang S., Seoul National University, KR

Highly porous nano carbon materials have been widely developed due to their advanced physical characteristics such as morphology, light weight, but more interestingly the possibility of designing the level of porosity as well as the [...]

Renewables-source Energy Storage for < $1.00 / kWh Capex as Hydrogen and Ammonia C-free Fuel Systems

Leighty B., The Leighty Foundation, US

Electricity systems will be inadequate to humanity's urgent task of rebuilding its largest industry -- energy -- from ~85% fossil today to 100% renewable sources by Year 2100. To supply all energy, from all sources [...]

Degradation Mechanisms in Electric Double Layer Capacitors Subjected to Voltage and Temperature Stress Testing

Peter A.S., Azarian M.H., Pecht M., University of Maryland, US

Due to their high power densities, electric double layer capacitors ¬¬(EDLCs) are used to supplement high energy density power sources (such as lithium ion batteries and fuel cells) in applications such as automotive kinetic energy [...]

Cluster-assembled carbon thin films and nanocomposites for electrochemical energy storage

Bettini L.G., Milani P., Piseri P., University of Milano, IT

Power generation and storage for microelectromechanical systems, miniaturized biomedical devices, sensors and integrated on-chip components, can significantly benefit from the fabrication and integration of planar thin film supercapacitors.
