FUNDAMENTAL STUDY ON THE SUPPRESSION OF DENDRITE GROWTH IN LITHIUM-METAL BATTERIES VIA CARBON NANORIBBONS THROUGH IN-SITU OPTICAL MISCROSCOPY

The purpose of this project was to study the underlying fundamental phenomena associated with the formation of dendrites in Lithium-metal batteries through the use of in-situ optical microscopy, and other techniques, and develop material solutions to suppress dendritic growth, such as carbon (graphene) nanoribbons (CNRs). Throughout the course of this effort, sixteen different slurry compositions were prepared and made into a total of 96 electrodes (six of each composition). These electrodes were built into in-situ optical cells and coin half-cells and then tested using in-situ optical microscopy and cycle testing. The results found that the inclusion of CNRs generally reduced the severity of dendrite formation.
