Conventional hydrogen-based systems designed to store electrical energy (from solar arrays, for example) typically feed electricity to a proton-exchange-membrane (PEM) electrolyzer to generate H2 from water. This H2 is then compressed and stored in a cylinder, or as a metal hydride in a canister containing a powdered metallic alloy. When electricity is required, H2 is supplied from the storage cylinder to...

A novel battery chemistry that uses a water-based electrolyte has allowed developer Aquion Energy Inc. (Pittsburgh, Pa.; www.aquionenergy.com) to achieve a low-cost and safe battery with long cycle life for stationary energy-storage applications. The Aquion battery technology, now entering its commercial launch process, employs an aqueous sodium-sulfate electrolyte. The water-based electrolyte makes the...

A high-throughput method for synthesizing ionic-liquid-containing electrolytes developed by Boulder Ionics Corp. (Arvada, Colo.; www.boulderionics.com) has been refined to enable its use in commercial production. Boulder Ionics had previously piloted the continuous process for producing advanced ionic-liquid (IL) electrolytes at high purity and low cost for use in next-generation batteries and...

Conventional lithium-ion batteries (LIBs) are unsuitable for high power applications as in electric vehicles, because they take a long time to charge, according to a team from the Interdisciplinary School of Green Energy, of the Ulsan National Institute of Science and Technology (Ulsan, South Korea; www.unist.ac.kr). Now the team, led by professor Jae-phil Cho, found...

A challenge in the development of polymer-electrolyte membrane fuel cells is the durability and electrocatalytic activity of platinum-based electrocatalysts. The sluggishness of the oxygen reduction reaction (ORR) causes the fuel cell performance to be limited by the cathodic reaction, and a high Pt loading is required for the cathode catalyst to achieve good activity for the ORR. Now researchers from the...

A team from the Korea Advanced Institute of Science and Technology (Kaist; Daejeon, South Korea: www.kaist.ac.kr) and Seoul National University (www.useoul.edu) led by Kaist’s professor Keon Jae Lee, claims to have developed the first prototype of a fully functional all-flexible lithium ion battery (LIB). The LIB is based on all-solid-state materials with an energy density of 2.2 x 103 µWh/cm3...

Mitsubishi Heavy Industries, Ltd. (MHI; Tokyo, Japan; www.mhi.co.jp) will begin developing basic technologies for a triple combined-cycle power-generation system that integrates solid-oxide fuel cells (SOFC) and a gas turbine combined cycle (GTCC) power generation system. Under the umbrella of the New Energy and Industrial Technology Development Organization (NEDO), the company will launch a two-year study...

A huge market for lithium ion batteries is expected to develop as car makers move toward electric vehicles. However, improvements in the batteries’ energy and power density are needed. It is also desirable to replace the common, high-cost lithium cobalt oxide cathodes with those based on more abundant and more environmentally friendly materials. Now, a group from the Dept. of Energy Engineering...

  Graphene from dry ice Researchers at Northern Illinois University (NIU; DeKalb, Ill.; www.niu.edu) discovered a new method for producing graphene that involves burning pure magnesium metal in dry ice. The method, which is capable of producing large quantities of graphene in sheets less than ten atoms thick, is simpler than conventional methods for generating graphene, and avoids hazardous chemicals...
