New rechargeable battery
New Lithium oxygen battery may have 5 to 10 times the storage cpacity of conventional lithium batteries. As the battery discharges, lithium ions from the electrolyte combine with electrons from the circuit and oxygen from the air around to produce lithium Li2O2. As the battery is charged up again, restocking it with lithium ions, the oxygen is emitted once again. Diagram here.
The porous carbon matrix which holds the oxide ought to be economical.
IMO: Could increase explosion risk during charging. Bugs in design could take 5-10 years to iron out but time and money might speed up the process.
