In a neutral atom, the protons in the nucleus are balanced by the electrons. An atom that has gained or lost electrons becomes negatively or positively charged and is called an ion.
Wrapping a large sheet of negativelycharged df-G around a positively charged Co3O4creates a very promising anode for high-performance Li-ion batteries.
