Abstract Anode‐free lithium (Li) metal batteries are promising candidates for advanced energy storage, attributed to their appealing characteristics such as high density, low cost, and convenient production. However, major challenges lie in the poor cycling rate performance owing inferior reversibility kinetics of Li plating stripping, which significantly hinder real‐world applications. Here, it is demonstrated that deoxyribonucleic acid (DNA), most important genetic material nature, can serve a highly programmable interphase layer innovation anode‐free batteries. It found abundant base pairs DNA contribute transient Li–N bonds facilitate homogeneous + flux, thus resulting excellent plating/stripping even at harsh areal current 15 mA cm −2 . The LiFePO 4 full based on an ultrathin (0.12 µm) ultralight (≈0.01 mg ) show CEs (≈99.1%) over 400 cycles, corresponding increase ≈186% compared with bare copper (Cu) foil. These results shed light programmability new family materials batteries, provide paradigm future battery toward programmability, sustainability, remarkable electrochemical performance.
