A micrographic and gravimetric study of intercalation and deintercalation of graphite fibers. By C. C. Hung. Abstract. Intercalation and deintercalation of Union Carbide P graphite fibers with liquid and vaporous bromine was studied gravimetrically and microscopically. The mass of the bromine intercalated fibers was found to be 17 to 20 Graphite fibers intercalated with Br 2, ICl, FeCl 3, and CuCl 2 were subjected to stability tests under four environments encountered by engineering materials in the aerospace industry. Monitoring the resistance of the fibers at ambient laboratory conditions revealed that only the FeCl 3 intercalated fibers were unstable, due to absorption of water from the :// "A Micrographic and Gravimetric Study of Intercalation and Deintercalation of Graphite Fibers," NASA TM ().

The mechanism of lithium intercalation in graphite film electrodes in In batteries and fuel cells, electrical energy is generated by conversion of chemical energy via redox reactions at the anode and cathode. As reactions at the anode usually take place at lower electrode potentials than at the cathode, the terms negative and positive electrode (indicated as minus and plus poles) are

In situ XRD study of Li deintercalation from two different types of LiMn 2 O 4 spinel. Solid State Ionics , (). Graphite, as a prevailing commercial anode material for lithium-ion batteries, delivers a gravimetric capacity of mAh g −1 and a volumetric capacity of mAh cm −3, much from meeting the increased requirement of consumers [24, ]. The structural changes upon intercalation via ‘staging’ The intercalation of secondary species like ions or molecules (generally referred to as intercalants) into the graphite host structure reveals a characteristic concentration-dependent feature, the so-called staging mechanism, as developed for the first time by Rüdorff and Hofmann in 45,46 According to this mechanism each A tin-decorated reduced graphene oxide, originally developed for lithium-ion batteries, has been investigated as an anode in sodium-ion batteries. The composite has been synthetized through microwave reduction of poly acrylic acid functionalized graphene oxide and a tin oxide organic precursor. The final product morphology reveals a composite in which Sn and SnO2 nanoparticles are
