The subway track system is a high-risk area where passengers are strictly prohibited from entering. Besides the high-speed running trains, the high voltage electricity present in between is also a fatal danger source. Some people who are not familiar with it may wonder, do the rails carry electricit

The mission of the pantograph is to maintain contact with the overhead contact line to supply power to high-speed trains. It presses against the contact line with a certain pressure to ensure the stability and continuity of power transmission. The contact surface of the pantograph is made of graphit

With the increasing global demand for renewable energy, battery technology, as a core component of it, has also received widespread attention. Among various battery technologies, graphite bipolar plates have become the focus of research due to their outstanding performance and broad application pros

Graphite bipolar plates are one of the core components in hydrogen fuel cells, mainly used for conducting electricity, separating reaction gases, and supporting the membrane electrode.

Activated carbon, with its well-developed pore structure and huge specific surface area, utilizes the principles of physical adsorption and chemical adsorption to adsorb various pollutants such as volatile organic compounds (VOCs), malodorous gases, and other contaminants in industrial exhaust gases

Coconut shell activated carbon has significant applications in seawater desalination projects. Coconut shell activated carbon is a porous adsorption material made from high-quality coconut shells through processes such as high-temperature activation and carbonization. It has a well-developed pore st

Don't underestimate the small black pieces of coconut shell activated carbon. It has a wide range of applications. The reason for its extensive use is mainly due to its well-developed pore structure and strong adsorption capacity. On the other hand, its catalytic properties also enable it to be appl

Vanadium redox flow batteries can be used as large-capacity energy storage power stations. In vanadium redox flow batteries, solutions of vanadium ions with different valence states are respectively used as the active substances for the positive and negative electrodes and are stored in separate ele

一. The Role of Graphite Fiber in Flow Batteries

Graphite felt, due to its excellent electrical conductivity and chemical stability, is usually used as the negative electrode material in batteries.
