Herein, a shape change-free and lithium-free anode that well controls the reversible Li plating-stripping is reported, which is composed of a highly-ordered hollow ZnO matrix with a surface-coated lithium-phosphorus-oxynitride (LiPON) layer. The ZnO matrix supplies sufficient cavities and lithiophilic sites to facilitate uniform Li plating/stripping within the hollow cavity, while the LiPON layer maintains stable solid-electrolyte interphase from mechanical and electrochemical damage. As a result, lithium is constrained within the cavity and the overall anode shape is effectively controlled during long-term and high-rate cycling. The assembled half-cell stably works at 1.2 mA cm−2 for 335 cycles with Coulombic efficiency of 98.8%. Without Li pre-deposition, full-cells using modified-LiFePO4 and LiNi0.5Co0.2Mn0.3O2 cathodes demonstrate 150-cycles lifespan and high energy density of 617 Wh kg−1 at 2C rate. © 2025 Wiley-VCH GmbH.enanode-free lithium metal batterieshigh ratelong-term stabilityreversibilityshape-controlledElectrolytesLithium batteriesLithium compoundsManganese compoundselectrolytelithiummetalAnode-free lithium metal batteryHigh rateHigher energy densityLithium metalsLithium phosphorus oxynitrideLong term stabilityOxynitride layersReversibilityShape-controlledZnO matrixanode electrodearticlecathode electrodecontrolled studyenergy resourceinterphaseZinc oxidejournal-article
