Abstract:
Lithium dendrite growth remains one of the major hindrances for its practical application. Here, we develop an ultrathin indium sheet to construct a stabilized lithium-rich hybrid anode with fast interfacial ion transport. The artificial alloy layer demonstrates an enhanced ionic conductivity that is an order of magnitude higher than that of the pristine solid electrolyte interphase. With the reduced diffusion barrier and improved charge transfer at the artificial interface, the hybrid anode realizes uniform lithium electrodeposition and considerable dendrite suppression. When coupled with LiNi5Co3Mn2O2 cathodes, this hybrid anode shows impressive reversibility.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
