Manganese, with a high reserve in Earth''s crust (1,000 ppm), is one of the essential elements in all known living organisms. 12 In addition, unlike highly reactive alkaline and alkaline earth metals, manganese is stable in air (Figure S1), making it possible to be handled and stored in ambient condition, further lowering its production and storage costs.
