A novel approach for suppressing the solvated lithium intercalation in graphite was developed by microencapsulating graphite with nanosized Ni-composite particles. The Ni-composite graphite showed great improvement in charge-discharge performance, coulomb efficiency, and cycling behavior when used as the negative electrode in a Li-ion cell with propylene carbonate (PC)-based electrolyte. For ex...

A solid-liquid method is used to synthesize the first stage bulk BaC6 graphite intercalation compound (GIC). This way of synthesis allows preparation and massive samples useful for crystal structure determination. Through a eutectic medium LiCl–KCl, by submerging platelet in barium-molten solution at 450 °C several days, obtained X-ray diffraction investigations allowed complete structural stud...

Detrimental co-intercalation and severe capacity fading were effectively prevented by the addition of fluoroethylene carbonate, resulting “absolute intercalation” enabled stable cycling graphite/LiFePO4 polymer electrolyte battery.

This study demonstrates a facile, mild and environmentally-friendly sustainable (soft processing) approach for the efficient electrochemical exfoliation of graphite using a sodium hydroxide/hydrogen peroxide/water (NaOH/H2O2/H2O) system that can produce high-quality, anodic few-layer graphene nanosheets in 95% yield at ambient reaction conditions. The control experiment conducted using NaOH/H2O...

Graphite is the most used lithium intercalation host for negative electrode of lithium-ion battery. Extensive research has been carried out to achieve high Coulombic Efficiency (CE) and long cycle life graphite anode. Here, LFP/graphite (graphite from Vendor 1) cells that undergo formation at 40 °C with either 1.2 M LiPF 6 dissolved in ethylene carbonate:dimethyl carbonate (EC:DMC), or carbonat...

With the aim to address the issues related to the regeneration of activated carbon used for wastewater treatment, a novel and state of the art water treatment technology (Arvia) was introduced at the University of Manchester, UK. This technology employs the adsorption of dissolved toxic pollutants present in water onto the surface of graphitic adsorbents followed by their quick and cheap electr...

A Pd-encapsulated graphite electrode was used as the negative electrode in Li-ion cells. Through dispersion of ultrafine nanoparticles of palladium on the surface of graphite, the interfacial properties of the carbon surface were modified. The presence of the palladium Ž . dramatically reduces the initial irreversible capacity of the graphite in propylene carbonate PC -based electrolyte. Pallad...
