IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

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. Image by Argonne National Laboratory.)

PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. —Jin et al. 2 in mole or 1.6:8.4

Investigating hexatitanate for lithium rechargeable battery anodes

Green Car Congress

Researchers in Europe have been investigating the potential of the protonated hexatitanate H 2 Ti 6 O 13 as an anode material for rechargeable lithium batteries. Results of their work suggests that the properties of H 2 Ti 6 O 13 seem to surpass those of the parent compound Li 2 Ti 6 O 13. Figure courtesy of J. Pérez-Flores.

Researchers directly visualize formation and disappearance of Li-O2 reaction products; insights to support development of rechargeable lithium-air batteries

Green Car Congress

During discharge and charge in UHV, Li ions reversibly intercalate/de-intercalate into/from the Li x V 2 O 5 electrode. 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

Univ. of Missouri team progressing with convection battery; enabling rechargeable lithium-metal batteries

Green Car Congress

The Li / Support is the electrode made possible with the convection battery technology. Galen Suppes say that they have further developed and validated the “convection battery” or “convection cell” technology originally announced in 2011 and 2012 ( earlier post ). Lower mass often translates to lower costs. Click to enlarge.

Stanford team identifies root cause of lithium intrusion into solid electrolytes

Green Car Congress

Lithium metal batteries with solid electrolytes are lightweight, inflammable, pack a lot of energy, and can be recharged very quickly, but they have been slow to develop due to mysterious short circuiting and failure. When that happens, the battery fails. Yet others theorize different forces are at play. La 3 Ta 0.4
