摘      要：Supercapacitor electrodes with porous structure based on renewable,eco-friendly and cost-effective materials have caused extensive concern in energy storage *** bread,the common food ingredient,mainly containing glucose polymers,can be a promising candidate to fabricate porous supercapacitor *** porous carbon aerogels by using sliced bread as the raw material were synthesized through a carefully controlled aerogel carbonization-activation ***,the specific surface area and the pore size distribution of the porous carbon were controlled by the activation temperature,which result in the varied performance of the carbon aerogel as a *** investigation measurements revealed that the hierarchical porous carbon aerogel shows an excellent capacitor behavior for construction of a symmetric supercapacitor,which demonstrated a high specific capacitance of 229 F·g-1 at discharge current of 0.2 A·*** addition,the fabricated supercapacitor displayed excellent capacitance retention of 95.5% over 5000 cycles.
