Development of thin film cathodes for lithium-ion batteries in the material system Li-Mn-O by r.f. magnetron sputtering

► Synthesis of 3 Li-Mn-O structures by one up-scalable thin film deposition method ► Formation of o-LiMnO2 by r.f. magnetron sputtering in combination with post-annealing ► Discharge capacity with o-LiMnO2 cathodes twice as high as for c-LiMn2O4 ► Thin film deposition of m-Li2MnO3 and o-LiMnO2
