'Nanoflowers' for Energy Storage and Solar Cells

North Carolina State University researchers have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flowers hold promise for next-generation energy storage devices and solar cells.

The Future of Iron-Air Batteries

A University of Southern California research team has developed a cheap, rechargeable battery that could be used to store energy at solar power plants for a rainy day. The air-breathing battery uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air — a process similar to rusting.

New Tech for Grid-Level Electrical Energy Storage

Electrical energy storage is the obstacle preventing more widespread use of renewable energy sources. Due to the unpredictable nature of wind and solar energy, the ability to store this energy when it is produced is essential for turning these resources into reliable sources of energy. The current U.S. energy grid system is used predominantly for distributing energy and allows little flexibility for storage of excess or a rapid dispersal on short notice. Drexel University researchers believe they have a solution.

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries

Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.

Coaxial Nanocable Could Aid in Energy Storage

Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.

Battery Options for Uninterruptible Power Supplies

The lead-acid battery was invented by the French physicist Gaston Planté in 1859, and is one of the oldest rechargeable battery technologies. For over 150 years, it has been the mainstay when a high-energy-capacity battery was required, and represents 70% of the secondary (rechargeable) batteries used worldwide. Even today, with the advent of higher-power-density and low-weight batteries, the lead-acid battery in all of its forms is the most commonly used battery type.

Boosting Nanowires for Better Batteries and Solar Cells

Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Tailoring Metal Oxides for Green Technological Applications

Harnessing solar energy can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice ‘sandwich.’ "Metal oxides can be tailored to meet all sorts of needs, which is good news for technological applications, specifically in energy generation and flat screen displays,” said Louis Piper, assistant professor of physics at Binghamton University.

Boosting Energy Efficiency of Multi-Hop Wireless Networks

Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.
