Pioneering Strategy of Circulation of Carbon Capture Toward Lithium‐Ion Batteries

The International Energy Agency (IEA) has emphasized that the priority of addressing climate change is to achieve "Net Zero by 2050." Unfortunately, the currently employed carbon dioxide removal (CDR) technology entails additional energy consumption, particularly when scaled to a global level. This work proposes a pioneering green technology integrating carbon capture and utilization in lithium silicate materials for lithium-ion batteries to realize "Reduction Carbon emission Batteries". Notably, the study is the first in analyzing the CO2 emissions occurring during materials fabrication and highlighting a high-energy-efficiency synthesis method superior to traditional approaches, capable of reducing CO2 emissions by more than 85%. Furthermore, the as-synthesized materials exhibit outstanding carbon capture ability by fast and efficient carbonation reactions, where the morphological and crystalline evolution are disclosed. Finally, the extreme stable cycling and fast-charging capabilities of the carbonated lithium silicate anode materials for Lithium Ion Batteries are demonstrated. This innovative interdisciplinary research will inspire the advancement of global green energy.
