摘要
Being an expected battery anode material, lithium metal suffers from dendrite growth during cycling, which is a fatal issue and aggravates the parasitic reactions with electrolytes and causes safety problem. Herein, we report that the MoP/C nanocomposite enables high–rate cycling of a lithium metal anode at an ultrahigh current density of 10 mA cm−2 for extended 500 h without dendrite growth. With the MoP/C nanocomposite Li anode, 500 cycle–life Li||LiNi0.8Co0.1Mn0.1O2 (NCM811) battery is achieved. These excellent performance can be attributed to the consistent Li+ flux within bulk lithium metal facilitated by the ion/electron conductive MoP/C nanocomposite. Our approach could lead to the stabilization of lithium metal anode and its potential application in high–energy–density batteries.
