Abstract Utilizing limited Li‐metal (<10 mAh cm −2 ) is desirable to achieve high‐specific‐energy batteries (LMBs). However, the rapid depletion and anode pulverization severely restrict cycle life of LMBs. Herein, 3D carbon‐based scaffold proposed as a host construct composite (ZOS‐CF@Li) with Li amount 8 via molten infusion assisted by lithiophilic ZnO/ZnS. In situ TEM reveals that ZnO/ZnS can spontaneously convert into ionically conductive 2 O/Li S electronically LiZn‐alloy, contributing faster ion/electron transport favorable dendrite‐free deposition. The experiment results combined theoretical calculations confirm inorganic Li‐salts high elastic modulus super lithiophilicity enable homogenous electric field distribution reduced Li‐diffusion energy barriers. Therefore, ZOS‐CF@Li exhibits stable cycling over 1100 h low overpotential under 5 in symmetric cell. Furthermore, performances coupled mass loading LiFePO 4 (20 mg LiNi 0.8 Co 0.1 Mn O (18 at N/P ratios 2.38 2.25 are achieved full‐cells, respectively. Li||LFP pouch‐cell maintain high‐capacity retention 97.7% after 90 cycles. This work will shed light on design for building Li‐anode high‐energy‐density
