USA: Better Lithium Air Batteries Invented at MIT Could Store 4 Times More Than Current Li-ion Batteries

A recent MIT invention could enhance the electricity storing ability of current lithium ion batteries by several times. Specifically, the batteries that were targeted were lithium-air, whose effectiveness has only recently been proven.

Basically, even the original versions of lithium air batteries are able to outperform classic lithium ion batteries by several times by using noble-metal-based catalysts. Replacing the heavy solid electrodes with a porous carbon electrode is the key to the performance enhancement. The latter combine oxygen from the air that flows through the system with lithium ions and form lithium oxides.
