Although promising electrode systems have recently been proposed1,2,3,4,5,6,7, their lifespans are limited by Li-alloying agglomeration8 or the growth of passivation layers9, which prevent the ...
The Li-ion battery consists of oxidized cobalt material on the positive electrode, carbon on the negative electrode, and lithium salt in an organic solvent as the electrolyte. Even though the widespread use of this chemistry is fairly novel, it is interesting to note that the processes in the battery are fairly simple to model compared to other chemistries.
Due to their abundance, low cost, and stability, carbon materials have been widely studied and evaluated as negative electrode materials for LIBs, SIBs, and PIBs, including graphite, hard carbon (HC), soft carbon (SC), graphene, and so forth. 37-40 Carbon materials have different structures (graphite, HC, SC, and graphene), which can meet the needs for …
