Lithium-Air Batteries: Technology Trends and Commercialization Prospects

Dublin, Oct. 10, 2013 (GLOBE NEWSWIRE) — Research and Markets (http://www.researchandmarkets.com/research/gmslkd/lithiumair) has announced the addition of the “Lithium-Air Batteries: Technology Trends and Commercialization Prospects” report to their offering.

Electric vehicles are facing numerous technological challenges to replace gasoline internal combustion engine-powered cars. One of the biggest problems is low energy density of currently available li-ion batteries, which allows a short driving range of 150 km/charge. To boost full-scale development of the EV market, replacing current internal combustion engine cars, it is necessary to develop EVs with a similar single charge range of more than 500km with internal combustion engine cars.

According to NEDO (Japan), the energy density limit of li-ion secondary batteries is expected to be up to 250 Wh/kg. To develop EVs with the 500km range, which is considered as a prerequisite for growth of the EV market, it is required to develop a new type of battery that has energy density of 700 Wh/kg or more. Among several candidate technologies, metal-air batteries such as lithium-air and zinc-air batteries are considered as the most promising.

The biggest advantage of metal-air batteries is very high theoretical energy density in spite of using oxygen as Natures inexhaustible source as well as eco-friendly characteristics. Comparing various metal-air batteries based on electric charge/discharge and other electro-chemical characteristics, lithium-air and zinc-air batteries are recognized as the most likely candidates for next-generation secondary batteries for EV applications. Especially, lithium-air batteries show a similar level of energy density (11,140 Wh/kg) with gasoline (13,000 Wh/kg), and this is also the highest level among metal-air batteries. These potentialities have directed many researchers to focus on lithium-air batteries rather than zinc-air batteries since the mid-2000s.
