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. —Kondori et al.

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. The technology allows lithium-metal batteries to be recharged without the dendrite failure (short circuit) that has prevented rechargeable lithium-metal batteries from being commercially viable.

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.

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

Green Car Congress

However, the limited performance of sodium-ion batteries has hindered large-scale application. Now, a research team from the Department of Energy’s Pacific Northwest National Laboratory (PNNL) has developed a new electrolyte enabling a high-voltage sodium-ion battery with greatly extended longevity in laboratory tests. 2 in mole or 1.6:8.4

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. The researchers focused mainly on the favorable cost-performance comparisons between their sodium-ion battery and lithium. —Lee et al.

Study identifies main culprit behind lithium metal battery failure; counters conventional wisdom

Green Car Congress

The researchers made their discovery by developing a technique to measure the amounts of inactive lithium species on the anode—a first in the field of battery research—and studying their micro- and nanostructures. The findings could pave the way for bringing rechargeable lithium metal batteries from the lab to the market.
