Graphite intercalation compound

Graphite intercalation compounds (GICs) are complex materials having a formula CXm where the ion Xn+ or Xn− is inserted (intercalated) between the oppositely charged carbon layers. Typically m is much less than 1.[1][2] These materials are deeply colored solids that exhibit a range of electrical and redox properties of potential applications.

Preparation, Characterization, and Structure Trends for

New graphite intercalation compounds (GICs) containing N,N-n-alkyl substituted pyrrolidinium cation intercalates (Pyn.m, n, m = alkyl chain lengths) are obtained via cationic exchange from stage-1 donor-type GIC [Na(ethylenediamine)1.0]C15. Powder X-ray diffraction and thermogravimetric analyses are used to determine the GIC structures and compositions. [Py4.8]C470.71DMSO and [Py8.8]C48 with

Preparation of high

2021/2/2Hard carbon is difficult to prepare as high-crystallinity synthetic graphite even with graphitization (over 2400 C), so only soft carbon has been used as a raw material for the preparation of synthetic graphite. Therefore, the selection of raw materials for synthetic graphite preparation is limited. In this study, synthetic graphite was prepared from hard carbon-based carbon black (HCCB)
