Fig. 3: The kinetics behavior of CuSe | |Mg batteries and lattice evolution of the CuSe cathode.
From: In-situ electrochemical activation accelerates the magnesium-ion storage
a Diffusion coefficient and (b) IR drop of CuSe/TFSI/Mg batteries in the second cycle treated with different methods. c Comparison of EIS results of SIM and ISEA methods in the first cycle. d CV curves of post-ISEA battery. HRTEM images of CuSe cathodes cycled with (e) ISEA and (f) SIM methods. The blue balls represent the Cu atoms and is used to illustrate the change in lattice spacing of the (100) crystal planes. The Se atoms are omitted for presentation clarity. Scale bars: 5 nm, insets: 2 1/nm.
