Abstract The commercial carbon‐based supercapacitor with high power ability (~5 kW kg −1 ) is still unable to fulfill the superhigh requirement of specific power‐type equipments (>20 ), such as rail transit facilities, electromagnetic and laser equipment. To unravel structure‐activity relationship electrochemical behavior densifying carbon a key overcome contradiction suitable mesoporous ratio highly‐densifying features toward requirement. Here, we built hierarchically‐densifying apocynum (HDMC) optimized by hierarchical activation method. More importantly, both isothermal desorption/adsorption high‐pressure mercury intrusion porosimetry methods were employed synergistically uncover microscopic surface network stacking mechanism macroscopic skeleton densification assembly mechanism. properties proved be co‐existed in HDMC, which favour rapidly ion/electron transferring electrochemically‐improving HDMC. A combination tap density (0.387 g cm −3 ideal microporous‐mesoporous system (23.1 % proportion mesoporous) have taken this HDMC provide super‐high (33.5 volume (9.37 L for HDMC‐based supercapacitor, more than those YP‐50F (14.9 @ 4.63 ). Therefore, work provides synergistic strategy incorporate densifying, reveals its further application supercapacitors.

China is one of the largest sugarcane industrial countries in world, and annual output bagasse waste abundant. Classical incineration, landfill, other treatment methods are inefficient seriously harmful to environment, so it urgent develop a new comprehensive utilization agricultural waste. In this work, residue converted biological activated carbon (BAC) through simple pre-carbonization KOH activation process, which then mixed with perovskite oxide BaCo0.5Fe0.5O3−δ (BCF) form BAC/BCF composite air electrode. assembled rechargeable zinc–air battery (ZAB) exhibits relatively good maximum power density 96 mW·cm−2 considerable long-term charge–discharge cycle stability over 250 h operation. These results indicate that BAC derived from promising potential material candidate for ZAB application, can realize high-value field efficient durable energy storage conversion devices.
