• synthesis, the preparation of 3D-Li2FePO4F requires the electrochemical ion-exchange of the Na-counterpart, and the corresponding Mn-based fluorophosphate has not been yet identified [16]. It is reasonable, that a substitution of Co2+ by Mn2+, which has the largest ionic radius, only takes place in a

• that are subsequently converted to Li2O2. To find out the most probable way for the generation of such building blocks, we performed a simple experiment purely based on the chemical generation of lithium peroxide in the ion exchange reaction KO2 + Li+ → K+ + ½ Li2O2 + ½ O2. Figure 3a demonstrates

• . If grafting is performed at the silanol groups as well as the benzene rings, resulting in a total loading of 1.65 mmol SO3H per gram as determined by measuring the ion exchange capacity (IEC), the changes in the texture properties for modified benzene-PMO are even more pronounced, as documented by a
