Mechanical deformability in next-generation batteries is vital for realizing wearable electronics and ensuring stability against volume fluctuations. This presentation introduces strategies achieving this via structural frameworks and intrinsic polymer design. First, regarding structural stretchability, we introduce a resilient MXene-CNT nano-accordion framework for anode-free sodium batteries that effectively accommodates severe volume expansion during cycling. Second, we focus on intrinsically stretchable, printable systems using functionalized organogels as stretchable binders. Significantly, we report all-material crosslinked solid polymer electrolytes (SPEs) for lithium metal batteries. Unlike liquid counterparts, these SPEs feature a robust crosslinked polymer network that suppresses dendrite growth and enhances safety without compromising flexibility. This approach enables high-performance batteries that remain stable even under dynamic wearing and stretching.
