Oxygen-rich carbon cloth as a lithium deposition host for stable lithium metal anodes.

ABSTRACT: Li metal is known as the most ideal anode material for Li-ion batteries due to its high theoretical capacity (3860 mA h g^-1) and low redox potential (-3.04 V vs. SHE). However, the dendrite growth and volume expansion caused by inhomogeneous and loose Li deposition limit the practical application of Li metal anode. Herein, oxidized carbon cloth (OCC) modified with oxygen-containing functional groups (-COOH, -C-OH, C[double bond, length as m-dash]O) is prepared by oxidation in a water bath environment. The polar oxygen-containing functional groups enhance the adsorption capacity of Li⁺, reduce the nucleation barrier, and effectively regulate the uniform distribution of Li⁺ on carbon fiber. Meanwhile, the large specific surface area of carbon fiber can
