Graphene oxide를 이용한 Nylon nano composite

compositeHard carbon & Soft carbonSoft carbon  The graphene layers are neatly stacked but there is less long-range order.Hard carbon The layers of carbon atoms are not neatly stacked, non-crystalline, macroscopically isotropic 0.38 nm spacing between planes means almost no volume change upon intercalation and potentially better cycleabilitySoft carbonHard carbonHard carbon & Soft carbonGraphite anode supplies power more stable than soft & hard carbon.The slope of soft & hard carbon’s curve can be an indicator to show the degree of charge & discharge.

compositions than uncoated one.In fact, there is a little difference of temperature of weight loss where the coated one has slightly higher temperature than the uncoated one.As a result, researchers concluded that Aluminum-Fluoride coatingimproves thermal stability protecting from Oxygen loss.39Up to now, we saw some thermal analyses used in cathode materials.Then, let’s look at the case of anode materials, for example, MCMB.These pictures are taken by SEM in condition of different time, and show the morphology of MCMB.40In this DSC curves, we can recognized that Lithium-un
