Efficient Lithium Growth Control from Ordered Nitrogen-Chelated Lithium-Ion for High Performance Lithium Metal Batteries.

ABSTRACT: Lithium (Li) metal has attracted significant attention as next-generation anode material owing to its high theoretical specific capacity and low potential. For enabling the practical application of Li-metal as an anode according to energy demands, suppressing dendrite growth by controlling the Li-ion (Li⁺) is crucial. In this study, metal-organic frameworks comprising bipyridinic nitrogen linker (M-bpyN) are proposed as 3-dimensional (3D) Li guiding matrix. The proposed approach creates ordered electronegative functional sites that enable the preoccupied Li⁺ in the ordered bipyridine sites to produce isotropic Li growth. The Li guiding matrix containing 3D ordered bipyridinic N sites introduces preoccupied Li⁺ sites that attract the Li growth direction, the
