General Observation of Lithium Intercalation into …
Lithium-ion batteries have exclusively employed an ethylene carbonate (EC)-based electrolyte to ensure the reversibility of the graphite negative electrode reaction. Because of the limitation of electrolyte compositions, there has been no remarkable progress in commercial lithium-ion batteries despite active research on positive electrode materials. Herein, we present a salt-superconcentrating
Allotropes of Carbon | Introduction to Chemistry
Allotropy is the property of some chemical elements to exist in two or more different forms, or allotropes, when found in nature. There are several allotropes of carbon. Allotropes of Carbon Allotropes of carbon: a) Diamond, b) Graphite, c) Lonsdaleite, d) C60 (Buckminsterfullerene or buckyball), e) C540, f) C70, g) Amorphous carbon, and h) single-walled carbon nanotube, or buckytube.
The uses of carbon and its compounds are extremely varied. It can form alloys with iron , of which the most common is carbon steel. Graphite is coined with clays to form the ''lead'' used in pencils used for writing and drawing.

Graphitic Carbon - an overview | ScienceDirect Topics
At the first charge, the organic solvent (propylene carbonate) is decomposed inevitably, whereby the SEI is formed at the expense of an irreversible loss of cell capacity of about 80 Ah kg −1. The lithium-ion conducting SEI consists of lithium salts (Li 2 O, LiF, Li 2 CO 3 etc.) and polyolefins, which are able to compensate volume changes in the graphite material during cycling without cracks.
