'Air fuelled' battery tech invented in Scotland • The Register
Lithium Oxygen Battery
that equates to a potential specific energy density of 3050 Wh/kg (around 19 times normal li-ion battery performance), handily trumping even the possibly-snazzy new lithium-sulphur tech which BASF have just jumped into. The scope is plainly there to achieve the five to tenfold storage boost that Professor Bruce is aiming at.
Lithium Oxygen Battery
On discharge, Li+ from the electrolyte and e- from the external circuit combine with O2 from the air, the process is reversible. We have demonstrated evolution of O2 on charging. Capacities as high as 855 mAhg-1 (based on the total mass of the cathode plus the additional mass of O2) have been achieved and values of 1220 mAhg-1 are, in principle, possible.
