| Abstract Scope |
Sodium-Ion Batteries (SIBs) are on the rise as a sustainable alternative to Lithium-Ion Batteries (LIBs) due to the similarities between Li and Na intercalation chemistry and the greater natural abundance of Na. A key challenge in SIBs lies in the development of compatible anode systems. Alloying/conversion-type electrodes, such as silicon (Si), offer higher theoretical capacities critical for applications like electric vehicles. However, their widespread adoption is hindered by significant volumetric changes during charge/discharge cycling, resulting in mechanical degradation leading to battery failure. To address this challenge, this work focuses on developing novel binders composed of MXene/self-healable polymer (MXene/SHP) composites. The benefits of these binders are two-fold: (1) Self-healing that enables reconnection of cracked Si particles, thereby improving battery life, and (2) MXene-enhanced conductivity and electrochemical activity, overcoming the limitations of conventional binders. This approach holds promise for improving the performance and longevity of conversion-type electrodes in SIBs. |
