The utility model provides a PH (Potential of Hydrogen) electrode washing device, and relates to an online submerged PH electrode washing device. The PH electrode washing device comprises a washing tank (1) and a washing pipe (8), wherein a PH electrode (2) is fixedly sleeved with the ...
electrolytic cell- a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen) electron gun- the electrode that is the source of electrons in a cathode-ray tube or electron mic...
Lithium metal is an ultimate anode for high-energy-density rechargeable batteries as it presents high theoretical capacity (3,860 mAh g−1) and low electrode potential (−3.04 V versus a standard hydrogen electrode)1,2. However, its low plating/stripping Coulombic efficiency (CE) is ...
16a-c). With SEI protection, improvement over cyclic stability is significant, with ~96% capacity retention after 500 cycles under the upper cut-off potential of 5 V and current density of 200 mA g−1 (Fig. 16d). As comparison, the capacity of unmodified graphite quickly decays ...
Standard hydrogen electrode and potential of zero charge in density functional calculations Methods to explicitly account for half-cell electrode potentials have recently appeared within the framework of density functional theory.

Cost-competitive fuel cells and water electrolysers require highly efficient electrocatalysts for the respective reactions of hydrogen oxidation and evolution, and oxygen evolution and reduction. Electrocatalyst activity and durability are commonly assessed using rotating disk electrodes (RDEs) or membrane el...
Fig. 11(b) compared the linear polarization curves of Pd/NCNTs and Pt/C drawn in HER process, the initial potential of Pd/NCNTs was −0.3 V at 60 mA cm−2, whereas that of Pt/C was −0.4 V at 40 mA cm−2, illustrating that the Pd/NCNTs showed improved electrocatalytic...
