Cascaded Spatial Confinement Enables Simultaneous Ultrahigh Energy and Power Densities in Planar Micro-Supercapacitors
, exceeding those reported for Zn//AC P-MSCs by several to tens of times, and surpassing nearly all existing Zn-based P-MSCs in areal performance. The approach demonstrates reliable universality across various P-MSC systems (eight types are verified). Integrated devices show notable advantages in powering miniaturized electronics and flexible displays, possessing a voltage output approximately 4.7 times that of a same-sized dry battery, and are also configured as emergency power chips to charge smartphones.
