Abstract Anion intercalation in graphite was investigated in the preceding paper. It was shown that about 140 mAh/g, corresponding to stage-two{prime} (PF{sub 6})C{sub 16}, of charge could be stored at potentials near 5 V vs. Li. Dual-graphite cells, where Li

Reversible Insertion of I–Cl Interhalogen in a Graphite

The results suggest three reversible steps: iodine plating on the host surface, oxidation to form I-Cl interhalides, and then intercalation into graphite. As a result, the graphite cathode delivers a high reversible capacity of 291 mAh g –1 with stable cycling performance.

A rechargeable Zn/graphite dual

2018/7/7Based on the composition of C 12 TfO graphite intercalation compound (GIC) (Ref. 46), a maximum capacity of 184.5 mAh g −1 can be achieved, indicating that there is a great prospect to further improve the overall performance of the Zn/graphite dual-ion cells.

Unlocking the True Capability of Graphite

Graphite-based dual-ion batteries (DIBs), which involve the intercalation of anions into the carbon layers, are promising for high-power applications. Many researchers inevitably choose ethyl methyl carbonate (EMC) as the electrolyte, as they observe superior electrochemical performances compared to other solvents. Here, we clarify the underlying reason why EMC is better. Specifically, EMC

Reversible Chemistry Clears Path for Safer Batteries

The energy output of the water-based battery reported in this study boasts 25% increased energy density of an ordinary cell phone battery based on flammable organic liquids, but is much safer. The new cathode is able to hold 240 milliamps per gram for an hour of operation, roughly twice that of a typical cathode currently found in cell phones and laptops.

ionic liquid-based electrolytes (e. g. 1-ethyl-3-methylimidazolium hexafluorophosphate) without any additional lithium salt (4). This system, a so-called dual-graphite cell, was based on the simultaneous intercalation of cations into the graphite anode and anions

Surface Layer Evolution on Graphite During

As recently shown, the most common anode material of the state of the art lithium ion batteries, graphite, can be used for sodium ion storage as well, if ether-based electrolyte solvents are used. These solvents cointercalate with the sodium ions leading to the highly reversible formation of ternary graphite intercalation compounds (t-GIC).

Synergistic PF6− and FSI− intercalation enables stable graphite cathode for potassium

Potassium-based dual ion batteries have emerged as promising alternatives to the prevailing lithium-ion batteries due to the advantages in cost and sustainability. Single-anion intercalation into graphite takes place on the cathode side, but it usually delivers a low
