Also known as lithium-air, the tech has been in the news before with promise for five to 15-times more efficiency than standard lithium-ion batteries.
Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their
weight. But such batteries have some pretty serious drawbacks: They waste much of the injected energy as heat and degrade relatively quickly. They also require expensive extra components to pump oxygen
gas in and out, in an open-cell configuration that is very different from conventional sealed batteries.
A Li-air cell creates voltage from the availability of oxygen molecules (O2) at the positive electrode. O2 reacts with the positively charged lithium ions to form lithium peroxide (Li2O2) and generate electric energy.
