Diagram of the STAIR (St Andrews Air) cell. Oxygen drawn from the air reacts within the porous carbon to release the electrical charge in this lithium-air battery. Lithium-air batteries use a catalytic air cathode in combination with an electrolyte and a lithium anode. Click to enlarge.
During discharge, Li ions meet with reduced oxygen on the surface of the Li x V 2 O 5 electrode forming Li 2 O 2 , which is decomposed upon recharge. The rechargeable Li?air The observational method this team developed could have implications for studying reactions far beyond lithium-air batteries, Yang Shao-Horn, the Gail E.
General schematic of a lithium-air battery. Leveraging expertise in materials science, nanotechnology, green chemistry and supercomputing, scientists at IBM Research’s Almaden lab in San Jose, California, are undertaking a multi-year research initiative around a grid-scale, efficient, affordable electrical energystorage network.
V), which renders the system with a low round-trip energy efficiency around 60%. V), which contributes to the low rechargeability. Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. mA/cm 2 —the lowest ever reported in metal-oxygen batteries, according to the team.
Researchers at the Illinois Institute of Technology (IIT) and US Department of Energy’s (DOE) Argonne National Laboratory have developed a lithium-air battery with a solid electrolyte. The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates. —Kondori et al.
The New York State Energy Research and Development Authority (NYSERDA) will award $8 million to help develop or commercialize 19 advanced energystorage projects. The 19 projects, which include two lithium-air efforts, will leverage $7.3 Next-generation lithium-ion rechargeable batteries. Murray, Jr.,
Gravimetric Ragone plot comparing energy and power characteristics of CNF electrodes based on the pristine and discharged electrode weight with that of LiCoO 2. Li-air (or Li-O 2 ) batteries are receiving a great deal of attention and funding as a high-density energystorage solution, especially for electric vehicle applications.
Schematic illustration of the aqueous rechargeablelithium battery (ARLB) using the coated lithium metal as anode, LiMn 2 O 4 as cathode and 0.5 It presents an energy density of 446 Wh kg -1 together with excellent cycling performance. Higher practical energy density. Higher energy efficiency. Wang et al.
Researchers at George Washington University led by Dr. Stuart Licht have introduced the principles of a new class rechargeable molten air batteries that offer amongst the highest intrinsic electric energystorage capabilities. In 2008 a zirconia stabilized VB 2 air battery was presented. Click to enlarge.
Furthermore, they added, the possibility for a rechargeable Li–O 2 /CO 2 battery based on Li 2 CO 3 may have merits in enhancing cyclability by minimizing side reactions. Lithium-air batteries, with a theoretical gravimetric energy density of ?3500 Earlier post.). —Lim et al.

Better Batteries - Batteries for Electrical EnergyStorage in Transportation (BEEST). Earlier post.). Earlier post.) Lead organization.
Last year, researchers at George Washington University led by Dr. Stuart Licht introduced the principles of a new class rechargeable molten air batteries that offer amongst the highest intrinsic electric energystorage capabilities. The iron molten air battery; illustration of the charge/discharge in molten carbonate.
Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy.
Lithium-air (Li-O 2 ) batteries are among the nost energy-dense electrochemical platforms for mobile energystorage, and are thus considered promising for electrified transportation. A number of severe challenges with the system need to be overcome first, however.
MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energystorage and delivery systems such as advanced fuel cells and lithium-air batteries.
The recent emerging demand for extended-range electric vehicles has stimulated the development of high-energystorage systems, especially the highly promising lithium–sulfur and lithium–air batteries, in which lithium metal anodes are employed. —Li et al. This is a really exciting observation.
Lithium-metal batteries are among the most promising candidates for high-density energystorage technology, but uncontrolled lithium dendrite growth, which results in poor recharging capability and safety hazards, currently is hindering their commercial potential.
The unit cost of batteries will decline with increased production and development; in addition, the energystorage (in kilowatt-hours) required for a given vehicle range will decline with vehicle load reduction and improved electrical component efficiency. Hybrid LDVs might reach 94 mpg (2.5 l/100 km) by 2050.
The new work, published in Science , shows that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The Waterloo team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries. —Xia et al.
In some studies it has been noted that the adequate BEV range perceived by the customer could be lower if the recharging time would be sufficiently short. For a 100 mile-range BEV requiring ≈21 kWh net , complete recharge could be accomplished within ≈60 min. Source: Gröger et al. Click to enlarge. kgH 2 /min.
