Here,we have studied two steps of phosphorus electrode reaction mechanisms for lithium-,sodium-,and magnesium-ion batteries[1-3]: i),the intercalation reaction mechanism,such as graphite anode and lithium cobalt oxide cathode for lithium-ion battery,which has a stable structure without chemical bond breaking for lithiation,leading to a long cycling life,but its specific capacity is low due to the limited lithium-storage sites; ii),the alloying/conversion reaction mechanism,such as silicon anode and sulfur cathode for lithium-ion battery,which has a high theoretical capacity,but decays rapidly because of its large volume expansion for lithiation.
