Abstract

Pseudocapacitive sodium ion storage materials

characterized by their combined high specific capacity and superior rate capability

are of significant value for the realization of sodium-ion capacitors with both high power and high energy density. This review systematically summarizes the charge storage mechanisms

electrochemical performance

and kinetic characteristics of pseudocapacitive materials

and provides an overview of the research progress in sodium-ion capacitors assembled using pseudocapacitive materials. The discussion primarily focuses on the structure-activity relationships between sodium ion storage mechanisms

structural regulation

and electrochemical performance intypical pseudocapacitive materials such as titanium-based

vanadium-based

and manganese-based. By deepening the understanding of the "sodium ion storage mechanism-performance synergy" in pseudocapacitive materials

this review innovatively proposes an advanced hybrid device design that couples high capacity battery-type positive electrodes with high-rate pseudocapacitive negative electrodes

thereby promoting the achievement of high energy density at high power densities and long cycle life in sodium-ion capacitors. Finally

an outlook on the future industrialization of high-performance sodium-ion capacitors is presented

targeting the demands of high-power application scenarios.
