Battery-like device that captures carbon dioxide while charging
Subject : Science and tech
Section : Technology
Context :
- The supercapacitor device, which is similar to a rechargeable battery, is the size of a coin, and is made in part from sustainable materials including coconut shells and seawater.
- Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges.
- Then, when it discharges, the carbon dioxide can be released in a controlled way and collected to be reused or disposed of responsibly.
- The supercapacitor could help power carbon capture and storage technologies at much lower cost.
- The most advanced carbon capture technologies currently require large amounts of energy and are expensive.
- The supercapacitor consists of two electrodes of positive and negative charge.
- The team tried alternating from a negative to a positive voltage to extend the charging time from previous experiments. This improved the supercapacitor’s ability to capture carbon.
