主　　题：integrated electrode-electrolyte optimization real-life applicable supercapacitor record-breaking lifespan 

摘      要：Aqueous supercapacitors(SCs)have been regarded as a promising candidate for commercial energy storage device due to their superior safety,low cost,and environmental ***,an age-old challenge of achieving both long electrode lifespan and qualified energy-storage property blocks their practical ***,we develop an electrode-electrolyte integrated optimization strategy to fulfill the real-life device *** optimization simultaneously regulates the nanomorphology and surface chemistry of the tungsten oxide anode,resulting in superior electrochemical performance given by an ideal“bird-neststructure with optimal oxygen vacancy status;the anodes interact with and are protected from dissolution and structural collapse by the rationally designed hybrid electrolyte with optimized pH and facilitated cation desorption ***,a record-breaking durability of no capacitive decay after 250000 cycles is *** the basis of this integrated optimization,the first aqueous pouch SCs with real-life practicability were manufactured by a soft-package encapsulation technique,which can steadily power commercial 3 C products such as tablets and smartphones and maintain safely working against extreme *** work demonstrates the possibility of using aqueous energy storage devices with enhanced safety and lower cost to replace the commercial organic counterparts for wide range of daily applications.
