Abstract
Three-dimensional hierarchical carbon nanotube/acetylene black (CNT/AB) networks are fabricated by a simple mixing method to enhance electronic contact among LiMn2O4 particles in the rechargeable hybrid aqueous battery (ReHAB), an aqueous Zn/LiMn2O4 battery system. The hierarchical and long-range conductive pathways lead to fast electronic transfer in the CNT/AB/LiMn2O4 cathode, which contributes to the outstanding rate performance (specific discharge capacity of 105 mAh g−1 at 10 C). Besides, the stable composite structure contributes to the good cycling performance and high reversibility (Coulombic efficiency of almost 100 % over 300 charge-discharge cycles at 4 C). This hierarchical conductive network design is particularly useful for energy storage applications operated at high charge-discharge rate.
