It has been proposed that increased graphene interlayer spacing increases lithium ion charge capacity ( DOI: 10.1021/nl800957b ). In addition, in a recent conversation someone told me that graphene sheets tend to stack together during electrochemical cycling, which reduces performance. Is anyone aware of any studies that measured the graphene stacking distance as a function of electrochemical cycling?
Dear Jacob
Yes, graphene nano sheets would definitely be stacking as a result of being used in electro-chemical cycle and this stacking behavior will increase with the time span. You can have more insights from the literature like following

Hope it help,
