*Abstract

The metal-CO2 battery developed by Cornell researchers stores electrical energy via reaction between the metal and the CO2 gas to produce a metal carbonate. The new metal-CO2 batteries present an attractive new technology platform since they consume CO2 emissions and have relatively high capacity at moderate temperatures. Various metals can be used as anode materials, with lithium yielding the highest capacity at up to 2500 mAh/g. A proof-of-concept battery cell was also demonstrated based on a sodium-air battery configuration with promising results.

 

Potential Applications: carbon capture, batteries, i.e. for electronic devices, electric vehicles, etc.

 

Advantages:

• Sustainability - combines CO2 capture with conversion into electrical energy
• High capacity at 100 degrees Celsius
