title: Lithium cycling in a self-assembled copper chloride-polyether hybrid electrode.
abstract: Atomic-scale integration of polyether molecules and copper(II) chloride layers in a two-dimensional perovskite affords, to the best of our knowledge, the first example of extended Li(+) cycling in a metal chloride electrode. The hybrid can cycle over 200 times as a cathode in a lithium battery with an open-circuit voltage of 3.2 V. In contrast, CuCl2 alone or the precursors to the hybrid cannot be cycled in a lithium battery, demonstrating the importance of the layered, organic-inorganic architecture. This work shows that appropriate organic groups can enable Li(+) cycling in inexpensive, nontoxic, metal halide electrodes, which is promising for large-scale applications.
