A patented process produces battery-grade lithium
Lithium producer Galaxy Resources Ltd. (Perth, Western Australia; www.galaxylithium.com) says that lithium carbonate product from its wholly owned Jiangsu Lithium Carbonate Plant has achieved battery grade quality using the company’s patented process (flowsheet). The Jiangsu plant is located in the Yangtze River International Chemical Industrial Park of the Zhangjiagang Free Trade Zone in...

Quick-charging lithium ion batteries on the horizon
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 little gold can reduce the Pt loading in fuel cells
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...

This fully functional Li-ion battery is flexible
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...

The quest for a more-efficient gas-fired power generator
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 high-performance electrode material for lithium-ion batteries
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...

Fuel-cell anode
A new anode material with nanostructured interfaces between barium oxide and nickel prevents deactivation by coking in solid-oxide fuel cells (SOFCs) using carbon-containing fuels. The material offers a path to low-cost, low-emission SOFCs that can convert gasified carbon fuels...

August Chementator Briefs
  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...
