Energy storage carbon felt

Are carbon felt electrodes a good choice for large-scale energy storage?

They are considered an excellent choice for large-scale energy storage. Carbon felt (CF) electrodes are commonly used as porous electrodes in flow batteries. In vanadium flow batteries, both active materials and discharge products are in a liquid phase, thus leaving no trace on the electrode surface.

Is carbon felt a good electrode?

The optimized carbon felt (1C-CF) showed excellent electrochemical performance, maintaining 71.8% energy efficiency at 250 mA cm -2 and 77.2% over 450 cycles at 150 mA cm -2, demonstrating good electrode stability. 1. Introduction

What is the structure of carbon felt?

The characteristic structure of the graphite layer on the surface of the modified carbon felts was revealed by XRD patterns. Surface analysis by XPS further confirmed that all carbon felts were composed of oxygen and carbon components.

How is carbon felt made?

The commercial carbon felt (5 mm thick) was purchased from Liaoning Jingu Carbon Materials Co., Ltd. The pristine carbon felt was ultrasonically washed with deionized water and ethanol to remove surface impurities, and then dried in a vacuum oven at 80℃ for 12 hours.

How do we construct a favorable surface structure of carbon felt?

In summary, our work successfully constructed a favorable surface structure of carbon felt through thermal treatment, followed by the deposition of functional nano-carbon layers using low-temperature unbalanced magnetron sputtering.

How is a nano-carbon layer constructed on carbon felt?

A nano-carbon layer with fine nanoparticles and rich oxygen functional groups was constructed on carbon felt via unbalanced magnetron sputtering and heat treatment.
