The numerous grainboundaries solid electrolyte interface, whether naturally occurring or artificially designed, leads to non-uniform Li metal deposition and consequently results in poor full-battery performance. Herein, a lithium-ion selective transport layer is reported achieve highly efficient dendrite-free lithium anode. layer-by-layer assembled protonated carbon nitride nanosheets present uniform macroscopical structure without grainboundaries. with ordered pores basal plane provides high-speed channels low tortuosity. Consequently, the 324 Wh kg−1 pouch cell exhibits 300 stable cycles capacity retention of 90.0% an average Coulombic efficiency up 99.7%. ultra-dense anode makes current collector-free possible, achieving high energy density long cycle life 7 Ah (506 kg−1, 160 cycles).

The demand for sustainable and stretchable thin‐film printed batteries bioelectronics, wearables, e‐textiles is rapidly increasing. Recently, we developed a fully 3D‐printed soft‐matter Ga‐Ag 2 O battery with 3R characteristics: resilient to mechanical strain, repairable after damage, recyclable. This achieved record‐breaking areal capacity of 26.37 mAh cm −2 , increasing 30.32 10 cycles under 100% strain. performance stems from the synergistic effects gallium's liquid metal properties styrene‐isoprene‐styrene polymer in anode. Gallium's high specific (1153.2 g −1 ), deformability, self‐healing abilities, supported by its supercooled phase, significantly enhance battery's resilience efficiency. However, cathode's lower theoretical capacity, due Ag (231.31 remains limitation. Traditional O‐carbon black‐styrene‐isoprene‐styrene cathodes experience rapid decay as only surface area active materials interacts electrolyte. To overcome this, designed carbon‐filled foam electrode using sacrificial sugar template, effective area. optimization enhanced ion‐exchange efficiency, cyclability, achieving 221.16 . Consequently, attained record 40.91 —double that nonfoam electrodes—and exhibited fivefold improved charge–discharge cycles. Using ultrastretchable Ag‐EGaIn‐styrene‐isoprene‐styrene carbon current collectors, increased 33% 50% Integrated into smart wristband temperature monitoring, demonstrated promise wearable electronics.
