“…A simplified relationship between the crystallographic structure of carbon, as represented by d(002) spacing, and its reversible Li storage capacity has been proposed (13)(14)(15). Published data for Q rev obtained with various carbonaceous materials, ranging from highly ordered graphite to highly disordered carbon, are plotted as a function of their d(002) spacing in Figure 3.…”

Graphitized carbons have played a key role in the successful commercialization of Li-ion batteries. The physicochemical properties of carbon cover a wide range; therefore identifying the optimum active electrode material can be time consuming. The significant physical properties of negative electrodes for Li-ion batteries are summarized, and the relationship of these properties to their electrochemical performance in nonaqueous electrolytes, are discussed in this paper.

“…Carbonaceous materials have received considerable interest as anodic materials for use in lithium ion secondary batteries [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. A number of carbonaceous materials have been investigated to find the best performances (large discharge capacity, small irreversible capacity or high coulombic efficiency, low discharge potential for obtaining high voltage), and low cost for mass production.…”

“…11 As a result, the widely accepted understanding is as follows: graphite with a higher graphitization degree, i.e., lower degree of random stacking, tends to have narrower interlayer space and deliver a higher capacity. [12][13][14] Conversely, the presence of a turbostratic structure of graphite, which has misorientation in the stacking of sp 2 carbon layers and a longer interlayer distance, reduces the reversible capacity 12 . For this reason, natural graphite, which is likely to have high crystallinity and narrower interlayer space of carbon layers, shows a higher capacity than synthetic graphite.…”

An effect of crystallinity of graphite on formation of graphite intercalated compounds (GICs) and reversibility in K cells was studied by comparing that of lithium-ion batteries. Though high reversible capacities and coulombic efficiencies of graphite electrodes in K cells were achieved during initial cycles regardless of the crystallinity, high crystallinity graphite demonstrated less potential-hysteresis and superior capacity retention to low crystallinity graphite. Operando XRD measurement confirmed similar staging process of K-GICs for both graphite, however, high crystallinity graphite was transformed into higher crystallinity of K-GIC as well as higher reversibility of potassium de-/intercalation than low crystallinity graphite. A turbostratic disorder in low crystallinity graphite led to redox-potential split and lower crystalline K-GIC and potassium-extracted graphite. Thus, the 2 crystallinity of graphite, which includes coherence length and the degree of random stacking, is found to be a predominant factor for highly reversible potassium intercalation, which differs from the lithium case. We concluded that the high crystallinity is of importance for the application of graphite to longlife potassium-ion batteries.
