Researchers from the Illinois Institute of Technology (IIT), Argonne National Laboratory, and the University of Illinois at Chicago have developed a room-temperature solid-state lithium-air battery that is rechargeable for 1,000 cycles with a low polarization gap and can operate at high rates. Ngo, Paul C. Redfern, Christopher S.
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.
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. A lithium-air battery based on lithium oxide (Li 2 O) formation can theoretically deliver an energy density that is comparable to that of gasoline.
It''s hard to keep track of all the future battery technology candidates, but lithium-air battery technology is among the most widely-researched. Its biggest draw is the potential to store three times the energy in batteries the same size and weight of today''s electric vehicles--providing huge increases in range.
General schematic of a lithium-air battery. The team plans to explore rechargeable Lithium-Air systems, which could offer 10 times the energy capacity of lithium-ion systems. Original lithium-air batteries—aqueous batteries, or with an aqueous electrolyte/air interface—were primary cells—i.e.,
So far, scientists have struggled to find batteries for electric cars that match the huge amounts of energy stored in a gallon of gasoline or diesel. Fossil fuels may not be the cleanest way of powering us between two points on a map, but there''s little doubt they offer convenience.
The carbon nanofiber electrodes are substantially more porous than other carbon electrodes, and can therefore more efficiently store the solid oxidized lithium (Li 2 O 2 ) that fills the pores as the battery discharges.

The US Department of Energy (DOE) has awarded 24 million hours of supercomputing time to investigate materials for developing lithiumair batteries, capable of powering a car for 500 miles on a single charge. Argonne is committed to developing lithiumair technologies. Earlier post.)
In an open access paper published in the International Journal of Smart and Nano Materials , researchers from the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences review significant developments and remaining challenges of practical Li–air batteries and the current understanding of their chemistry.
The 19 projects, which include two lithium-air efforts, will leverage $7.3 Also, the system can provide backup electricity during an outage and, during normal operation, allow customers to draw on the stored energy to reduce both their peak electric grid demand and the utility charges associated with peak demand. Murray, Jr.,
Argonne National Laboratory, near Chicago, will host on 3-4 May 2010 the symposium “ Beyond Lithium Ion: Computational Perspectives ” to discuss research opportunities in electrochemical energy storage, specifically, lithium-air batteries for transportation.
By storing energy and bearing mechanical loads, structural batteries reduce the amount of conventional structural materials required by devices. Unfortunately, more energy-dense, li-based chemistries such as lithium-sulfur and lithium-air can also experience thermal runaway. —Hopkins et al.
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. Given the role of carbon as a possible porous positive electrode for nonaqueous Li?
Vorbeck, a manufacturer and developer of applications using its proprietary graphene material ( earlier post ), optioned the technology for use in a graphene-based electrode for lithium-air and lithium-sulfur batteries.
Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. However, the technology has several holdups, including losing energy as it stores and releases its charge.The reaction mechanisms are, in general, not well understood.
The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. The all solid-state system would enable high energy density, high power density, and reversibility of a lithium-air battery, according to the claims. Earlier post.).
In addition to developing advanced materials for lithium-ion batteries, BASF is also researching future battery concepts such as lithium-sulfur and lithium-air. BASF has also taken a stake in Sion.) ( Earlier post.). Construction is underway and completion is expected in early 2014.
This process is less than 1% efficient at converting sunlight to stored chemical energy. Li-Air Battery : Development Of Ultra-high Specific Energy Rechargeable Lithium/Air Batteries Based On Protected Lithium Metal Electrodes. 4,973,724. 999,997.
Conventional lithium-air batteries draw in oxygen from the outside air to drive a chemical reaction with the battery’s lithium during the discharging cycle, and this oxygen is then released again to the atmosphere during the reverse reaction in the charging cycle. —Zhu et al.
Another attractive aspect of this technology is that lithium metal can be produced from salt solutions (e.g., In other words, energy from the sun can be “stored” in the metal, and then be used on demand by reacting the lithium in the fuel cell. Recharging the battery would be a matter of replacing the lithium metal cell.
The recent emerging demand for extended-range electric vehicles has stimulated the development of high-energy storage 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-sulfur and lithiumair batteries have the potential to store 10 times more energy in the same space as the current state-of-the-art lithium-ion batteries. However, the Li-metal electrodes in these next-generation batteries are especially prone to forming dendrites.
Typical thermal runaway of a Li-ion battery due to overcharging or internal shorts is not a possibility in Li-air batteries because of the rate-limited surface nature of the reaction, i.e., the reactant O 2 is not stored in the battery. Wilcke (2010) Lithium-Air Battery: Promise and Challenges. Resources. Girishkumar, B.
When it comes to volumetric energy density, iron–air batteries could perform even better with 9,700 Wh/l—almost five times higher than today’s lithium-ion batteries (2,000 Wh/l). The oxygen required for the reaction can be drawn from the surrounding air so that it does not need to be stored in the battery.
Also on the list of five is the arrival of advanced batteries, including air batteries (e.g., Lithiumair), but targeted initially at small devices. Batteries today have a number of problems, chiefly, the heavy metal-oxides used inside the battery greatly limit the amount of energy it can store, IBM notes.
Some other Battery news are, New developments and experiments in battery chemistries like lithium-air and magnesium-ion are going on. The batteries that use sodium instead of the pricey and rare lithium are the ones that are the closest to being on the market.
From how much they cost and weigh to the amount of power they store and how long they take to charge, electric vehicle (EV) batteries have a significant impact on EVs themselves, the EV industry as a whole, and ultimately EV buyers.
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.
