Abstract

Abstract : Herein, carbonized nickel metal organic framework scaffolds at nickel foam (CNS@NF) were fabricated to regulate Li-ion plating/stripping in lithium cells. Abstract : Herein, carbonized nickel metal organic framework scaffolds at nickel foam (CNS@NF) were fabricated to regulate Li-ion plating/stripping in lithium cells. CNS@NF would contribute to uniform Li nucleation and low overpotential due to the small lattice mismatch ratio and homogenous lithiophilic sites. Moreover, the spongy structure of the carbonized MOF can reduce the local current density by smoothening the sharp edges of NiO. Owing to these advantages, both the symmetric cells and full cells exhibited excellent electrochemical performance.
