A New Tool For Mapping The NanoElectrochemical Characteristics of Battery Interfaces: AFM SECM
October 2020
An Exemplary Publication By A Nanonics Customer: Kiran Mahankali, Naresh Kumar Thangavel, and Leela Mohana Reddy Arava, “In Situ Electrochemical Mapping of Lithium–Sulfur Battery Interfaces Using AFM–SECM,” Nano Lett. 2019, 19, 8, 5229–5236 https://doi.org/10.1021/acs.nanolett.9b01636
Lithium based batteries drive many of the electronics that we use in our daily lives. Significant interest has developed on a variant known as lithium-sulfur (Li-S) batteries. These batteries could result in a significant advance in achieving more power with lighter and smaller packaging. However, several challenges lie ahead for their development. These mainly are related to the electrochemical processes that underlie the function of these batteries and result in the irreversible deposition of insulating materials that perturb battery function.
Scanning electrochemical microscopy (SECM) is a powerful method to look at local electrochemical changes and can even image the nature of these changes. Thus, its application has great potential to affect new understandings that could lead to improvements in such battery function...
