New lithium-oxygen battery greatly improves energy efficiency, longevity
New chemistry could overcome key drawbacks of lithium-air batteries.

Instead, the oxygen stays inside the solid and transforms directly between its three redox states, while bound in the form of three different solid chemical compounds, Li2O, Li2O2, and LiO2, which are mixed together in the form of a glass. This reduces the voltage loss by a factor of five, from 1.2 volts to 0.24 volts, so only 8 percent of the electrical energy is turned to heat.

Interesting proposal. But I question the stability of Li2O2 and LiO2.

Does anybody have any references for further reading?

Search for solid state batteries. I've heard anecdotally that they have 3 times the energy density, charge in minutes, and are non-flammable. I'm not sure about cycle longevity.
