Abstract: High-performance all-solid-state rechargeable batteries with highly wearable, deformable, and waterproof features have attracted considerable attention for their promising applications in next-generation wearable electronics. Herein, a flexible all-solid-state in-plane Zn-polyaniline (PANI) micro-battery with concentric circle structure is reported by directly electrodepositing both positive and negative electrode materials on tyrene-isoprene styrene rubber (SIS) substrate. As-fabricated battery delivers a high specific area capacity of 250 mu Ah cm(-2), a high energy density (0.25 mW h cm(-2)) and a high power density (0.99 mW cm(-2)) as well as excellent cyclin stability (68% capacity retention after 1200 cycles). More importantly, the concentric circle structured micro-battery exhibits superior mechanical flexibility, reasonable stretchability, outstanding waterproof ability, and temperature resistance up to 80 degrees C and excellent integratability with wireless charging coils.
