and Ag/AgCl electrodes were used as counter and reference electrodes, respectively. All potentials are reported relative to the Ag/AgCl reference electrode (3 M KCl). For calibration plots, the working electrode was rotated using a Pine model MSRX rotator.

Frontiers

Edge-plane pyrolytic graphite electrodes (GE) of 5 mm diameter were from PINE (Durham, NC, United States). GE have been employed extensively in bioelectrochemistry because of the relatively smooth surface area and the good compatibility with proteins and microorganisms ( Zafar et al., 2009 ; Tasca et al., 2015 ; Venegas et al., 2017 ).

Pyrolytic graphic is the same as regular graphite (sheets of hexagonally bonded carbon atoms), but in pyrolytic graphite the sheets are all arranged in the same direction, in a flat pancake. In normal graphite there are zones of order like that, but as a whole the orientation of the sheets is random, making ordinary graphite an isotropic material.

Rechargeable Dual‐Ion Batteries with Graphite as a

Rechargeable graphite dual‐ion batteries (GDIBs) have attracted the attention of electrochemists and material scientists in recent years due to their low cost and high‐performance metrics, such as high power density (≈3–175 kW kg −1), energy efficiency (≈80–90%), long cycling life, and high energy density (up to 200 Wh kg −1), suited for grid‐level stationary storage of

Carbon fibers

Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. [citation needed] Carbon fibers have several advantages including high stiffness, high tensile strength, low weight to strength ratio, high chemical resistance, high temperature tolerance and low thermal
