Is graphite a positive or negative electrode?
Graphite can function as both a positive and a negative electrode depending on the context.
In certain electrochemical systems, such as lithium-ion batteries, graphite is commonly used as a negative electrode (anode).
In other applications, such as certain types of fuel cells, graphite may serve as a positive electrode (cathode).
The role of graphite in an electrochemical system is determined by the specific design and requirements of that system.
