Metal Halide Perovskites as anode materials in hybrid organic inorganic lithium ion batteries — •Tom Wickenhäuser1, Shangpu Liu2, Lennart Singer1, Felix Deschler2, and Rüdiger Klingeler1 — 1Kirchhoff Institute for Physics, Heidelberg, Germany — 2Physikalisch-Chemisches Institut, Heidelberg, Germany
We report on the characterisation of metal halide perovskites as electrode materials in hybrid organic-inorganic lithium-ion batteries. In particular, MAPbBr3, one dimensional EAPbI3 and two lead-free perovskites CsMnBr3 and EA4Bi2Br10 are investigated as anode material for lithium-ion batteries. Cyclic voltammetry as well as galvanostatic cycling measurements were performed to elucidate the electrochemical reaction mechanism with a special focus on the ionic and electronic transport characteristics. Additional investigations on the influence of different electrolytes on the electrochemical performance revealed an improved cycling stability for 1M LiTFSI in DOL/DME (1:1) compared to 1M LiPF6 in EC/DMC (1:1). In the context of these studies; promising first cycle capacities of 560 mAh g−1 for MAPbBr3, 440 mAh g−1 for EAPbI3, 330 mAh g−1 for EA4Bi2Br10 and 201 mAh g−1 for CsMnBr3 were achieved.
