Graphite anodes have multiple purposes other than just lithium-ion batteries. They are employed in electrochemical reactions for instance water electrolysis wherein they aid the splitting of water into hydrogen and oxygen using graphite. Graphite anodes are also used in other types of 电池 (like the sodium-ion battery) and energy storage. Synthetic graphite anode is a key material used in this transition to renewable energy because it allows us to store the intermittent nature of renewables, such as solar and wind.
