Scientists at Cambridge University have published a research paper in the journal <i>Science</i> that details how the team overcome obstacles in the development of [http://www.independent.co.uk/news/uk/cambridge-chemists-make-breakthrough-with-ultimate-battery-which-can-power-a-car-from-london-to-a6716046.html lithium-air batteries].
Lithium-air batteries have the potential to store more energy than other battery types. They have the potential to store 5–15 times the specific energy of current lithium-ion batteries. For comparison, the energy density of gasoline is approximately 13 kW·h/kg while the theoretical energy density of the lithium-air battery is 12 kW·h/kg.<ref>https://en.wikipedia.org/wiki/Lithium%E2%80%93air_battery#cite_note-BatteryMaterials-10</ref><ref>http://sciencewatch.com/articles/lithium-air-batteries-are-great-so-are-their-problems</ref><ref>http://arstechnica.com/science/2015/10/lithium-air-battery-research-shows-potential-paths-to-next-gen-batteries/</ref><ref>http://www.sciencemag.org/content/350/6260/530.abstract</ref><ref>http://singularityhub.com/2014/10/28/new-solar-cell-doubles-as-battery-to-store-the-energy-it-creates/</ref>
Another advantage is that lithium-air batteries have a solid-state design that is attractive from a safety standpoint. It eliminates the possibility of rupture and ignition.
Maybe an electric-sail hybrid is the answer?
