Malleable textured Li for practical lithium metal batteries over 8,902 W kg⁻¹

High-power lithium (Li) metal batteries (LMBs) are pivotal for the low-altitude economy, yet their rate performance remains inadequate for urgent demands due to stress-induced ion transport disruption under practical current densities. Here, we synthesize a malleable textured Li foil via cryogenic rolling for high-rate LMBs. The high yield strength of the Li foil mitigates localized stress concentrations, thereby ensuring highly efficient ion transport pathways. The integration of tough Li foil with low-diffusion-barrier crystal planes significantly accelerates Li atom diffusion and enhances surface kinetics, enabling uniform plating/stripping under high current densities. Batteries assembled with the malleable textured Li metal deliver a peak power density of 8,902 W kg⁻¹ (30 C). Meanwhile, practical 10 Ah pouch cells (427.1 Wh kg⁻¹) retain 84.2% of their initial capacity over 420 cycles. This strategy constitutes a decisive step toward high-power, long-endurance LMBs, unlocking their potential for electric aviation applications.
