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.
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.
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. Lithium-ion rechargeable (secondary) batteries are based on a pair of intercalation electrodes. Adapted from Ogasawara et al.
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. —Zhang 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. Carbon promotes electrolyte decomposition during discharge and charge in a Li?O
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.
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. —Luo et al.
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.
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.).
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.
An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V in O 2 (gas) → O x− (condensed phase), and η charging > 1.1
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. 1,000,000. 1,000,000.
IBM and its partners have launched a multi-year research initiative exploring rechargeable Li-air systems: The Battery 500 Project. Fortunately, an energy density of 1700 Wh/kg for the fully charged battery corresponds only to 14.5% of the theoretical energy content of lithium metal. Earlier post.) Electrical energy efficiency.
Using in-situ electrochemical atomic force microscopy ( in-situ EC-AFM) at the Center for Nanophase Materials Sciences at ORNL, they were able to observe how deposits of iron hydroxide particles (Fe(OH) 2 ) form at the iron electrode under conditions similar to those prevalent during charging and discharging.

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.
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. shake and dial.
Customers desire vehicles with affordable price tags, quicker charging time, and greater ranges and developing battery technology is a great way to answer these questions. Some other Battery news are, New developments and experiments in battery chemistries like lithium-air and magnesium-ion are going on.
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.
