Population explosion has led to the rapid revolution of science and technology. High energy demand has urged for new and efficient energy conversion and storage systems. Lithium ion batteries (LIBs) have high potential window, high capacity and high stability but it suffers from high cost and low safety. Therefore, many alternative batteries including sodium (NIBs), potassium (KIBs), aluminum (AIBs) and dual ion batteries (DIBs) have been introduced. One of working principle of these batteries is based on cation or anion intercalation in the graphite layers, which are known as formation of graphite intercalation compounds (GICs). Recently, the studies based on reaction mechanism to improve the performance of the batteries have been elucidated. In this review, a view on reaction mechanism of polyatomic ions intercalated into GICs, structure of intercalated polyatomic ions, structure of accommodated GICs and staging are provided. The current limitations and our prospects on polyatomic ions intercalated batteries are also discussed. |

Recently, aluminum ion batteries (AIBs) have attracted great attention across the globe by virtue of its massive gravimetric and volumetric capacities in addition to its high abundance. Though carbon derivatives are excellent cathodes for AIBs, there is much room for further development. In this study, flexuous graphite (FG) was synthesized by a simple thermal shock treatment and, for the first time, an Al/FG battery was applied as a cathode for AIBs to reveal the real-time intercalation of AlCl4- into FG with high flexibility using in situ scanning electron microscope (SEM) measurements exclusively. Similarly, in situ X-ray diffraction (XRD) and in situ Raman techniques have been used to understand the anomalous electrochemical behavior of FG. It was found that FG adopts a unique integrated intercalation–adsorption mechanism where it follows an intercalation mechanism potential above 1.5 V and an adsorption mechanism potential below 1.5 V. This unique integrated intercalation–adsorption mechanism allows FG to exhibit superior properties, like high capacity (≥140 mAh/g), remarkable long-term stability (over 8000 cycles), excellent rate retention (93 mAh/g at 7.5 A/g) and extremely rapid charging and slow discharging.
