Carbonaceous quantum dots/nan dots materials for potassium ion storage
Author(s): Melina Olmos*
Carbonaceous quantum dots/nanodots (CQDs/CNDs) have emerged as promising electrode materials for potassium ion batteries (PIBs) due to their unique structural and electrochemical properties. This abstract reviews the recent advancements and potential of CQDs/CNDs in PIB applications. The nanoscale dimensions of CQDs/CNDs offer high surface areato- volume ratios, facilitating efficient potassium ion adsorption and desorption kinetics. Surface functional groups on CQDs/CNDs further enhance potassium ion binding affinity and stabilize the electrode-electrolyte interface, contributing to improve cycling stability and electrochemical performance. Various synthesis methods allow precise control over the size, morphology, and surface chemistry of CQDs/CNDs, influencing their potassium ion storage capabilities. Experimental studies demonstrate that CQDs/CNDs exhibit high specific capacities, .. View more»
