“…The reversible capacity reaches a minimum at about 2000ЊC, where the sample mainly consists of organized carbon sheets with large turbostratic disorder which may have less capability to intercalate lithium than either the disorganized carbon or perfect graphite. 13,19 Despite the difficulty in quantitatively understanding the lithium intercalation process in various carbonaceous materials, it is clear that natural graphite or graphitized carbon is most likely to satisfy the requirement of high reversible capacity, low irreversible capacity loss, and flat voltage potential profiles desired for a carbon anode in lithium-ion batteries. In this study, we selected a series of purified natural graphite, graphitized coke, and mesophase carbon customized with high graphitization, high purity, and relatively low surface area to identify the most suitable carbon anode materials for lithium-ion batteries.…”

The electrochemical performance of a series of natural and synthetic graphite powders was investigated for their viability as anode materials in lithium‐ion batteries. The variation of the charge and discharge capacities can be qualitatively correlated to their structural and morphological differences. The specially treated natural graphite samples show excellent capacity and relatively small irreversible capacity losses. A noticeable percentage of the rhombohedral phase was observed in the natural graphite samples. The good electrochemical performance of these graphite powders may be attributed to the combination of low surface area and absence of exfoliation due to the presence of the rhombohedral phase and defects in the grain boundaries. Graphitized cokes generally exhibited larger irreversible capacity loss, and mesophase carbons produced relatively low reversible capacity. © 2000 The Electrochemical Society. All rights reserved.

“…250 mAh g −1 at C/10, which is equal to that of other soft carbons tested in similar condition. 26,27,28 When the applied rate was increased to 1C, the capacity of the electrode decreased to 175 mAh g −1 . During charge and discharge tests carried out at 5C, the electrode showed a capacity of 75-80 mAh g −1 .…”

The combined use of soft carbon (PeC) as anodic material, and propylene carbonate (PC) as electrolyte solvent is a promising strategy for the realization of high performance lithium-ion capacitors (LIC). PeC electrodes display a capacity of around 80 mAhg −1 during cycling carried out at 5C, which can be maintained for more than 10,000 cycles. This performance is higher than that displayed by most of the carbonaceous electrodes so far proposed for LIC. PC is known to be a safer electrolyte compared to mixtures of organic carbonates used so far in LIC, and therefore its use is beneficial for the realization of safer LIC. When a correct pre-lithiation process is applied, LICs based on PeC and PC display high performance in terms of capacity and cycling stability. When a current density of 10.6 mA/cm 2 (corresponding to 5.6 A/g) is applied to a LIC average energy and power of 21.7 Wh kg −1 and 4.1 kW kg −1 (based to the total active material), respectively, were achieved.

“…Soft carbon (SC) is the first carbonaceous material used in the first generation Li-ion cells, which was produced from petroleum coke. [12,[105][106][107][108][109] It can be produced from pitch or tar or by pyrolysis of organic polymers such as polyvinyl chloride in a low-oxygen atmosphere. [110][111][112][113] Unlike hard carbon, soft carbon, containing a semi-graphitic structure, has highly ordered graphitic domains arranged in a turbostatic disordered manner.…”

Carbon‐based materials have played a pivotal role in enhancing the electrochemical performance of Li‐ion batteries (LIBs). This review summarizes the significant developments in the application of carbon‐based materials for enhancing LIBs. It highlights the latest innovations in different types of carbon materials such as graphite, soft carbon, hard carbon, and various carbon nanostructures, including design and synthesis. Additionally, the feasibility of developing flexible self‐supported electrodes for wearable devices is underlined. More emphasis is given to elucidating the Li‐ion storage mechanisms inherent in various carbon materials, illustrating the variations in Li‐storage that arise as the structure transitions from order to disorder and from bulk to the nano realm. Furthermore, the use of carbon composites, which incorporate different alloy/conversion/intercalation type materials with carbon matrices, is discussed in view of their improved electrochemical performances in terms of energy density, power density, and cycling stability. The review underscores the growing importance of carbon materials in addressing the ever‐increasing demand for high‐performance energy storage solutions and also addresses the remaining challenges and future perspectives, aiming to provide future research directions.
