Recently, Professor Zhou Zhen of the School of Chemistry at Nankai University discovered a breathable carbon dioxide battery. This kind of battery uses graphene as the air electrode of the lithium carbon dioxide battery, and lithium metal as the negative electrode, absorbing the carbon dioxide in the air to release energy. The idea of ​​a rechargeable lithium-carbon dioxide battery was discovered in an experiment three years ago by Dr. Su Liwei, a member of the research group. He found that carbonates have a very high lithium storage capacity at the negative electrode of lithium-ion batteries and generate carbon dioxide bubbles during the reaction. Afterwards, Zhang Zhang, a doctoral student, began to establish a lithium-oxygen battery research platform. After repeated experiments by team members, he continuously improved the electrode performance. For the first time, graphene was used as an air electrode for a lithium-carbon dioxide battery, showing excellent performance and continuous charge and discharge 20 More times. This is the highest level so far. The improvement of the performance of lithium carbon dioxide batteries is due to the high conductivity and large specific surface area of ​​graphene, which provides a good place for electrochemical reactions. At present, although the research of rechargeable lithium-carbon dioxide batteries has just started, the basic principles are not yet fully understood, and the dynamic performance and charge-discharge cycle capability are poor, and further research is needed. However, experts believe that this research is of great significance in promoting the application of carbon dioxide in the field of energy storage and conversion, and in realizing the leap of lithium-oxygen batteries to lithium-air batteries. The related research results were published in Applied Chemistry (International Edition), one of the top three traditional top journals in chemistry, and were selected as hot topics by the editors. The study was funded by the National Natural Science Foundation of China and the Ministry of Education.
