Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. One reaction that hasn’t been fully explained is how oxygen blows bubbles inside a lithium-air battery when it discharges. The paper is published in the journal Nature Nanotechnology.

Lithium-air (or lithium-oxygen) batteries potentially could offer three times the gravimetric energy of current Li-ion batteries (3500 Wh/kg at the cell level); as such, they are looked to a potential solution for long-range EVs. Li 2 O 2 precipitate passivates the electrode surface hindering further electron transfer.

In the near-term (2012-2017), DOE sees an opportunity to more than double the battery pack energy density from 100 Wh/kg to 250 Wh/kg through the use of new high-capacity cathode materials, higher voltage electrolytes, and the use of high capacity silicon or tin- based intermetallic alloys to replace graphite anodes. —Blueprint.

Industry-wide cost estimates for battery packs for electric vehicles have declined by approximately 14% annually between 2007 and 2014, from above US$1,000 per kWh to around US$410/kWh, according to a systematic review of more than 80 different estimates by a team from the Stockholm Environment Institute.
