| 英文摘要 | rapid charge-discharge rate is an important feature of energy storage devices, but causes dramatic reduction in battery performance. in single flow zinc-nickel batteries (znbs), large polarization of nickel hydroxide electrode is an obstacle to realizing high charge-discharge rate without compromising battery performance. a novel cell structure with a serpentine flow field is designed to reduce the polarization of the positive electrode through enhancing mass transport. the power density is improved nearly fourfold by elevating charge-discharge current density from 20 ma cm(-2) to 80 ma cm(-2) for the first time. compared to traditional structure cell, the energy efficiency is improved 10.3% reaching to 75.2% at 80 ma cm(-2), which has a remarkable improvement. no obvious decrease of efficiencies is presented in the 70 charge-discharge cycles. this provides a feasible method to improve the charge-discharge rate with high performance and boosts the practical application progress of znbs.
