摘要
The need for the development of efficient electrochemical energy storage devices with high energy density, power density and safety is becoming more and more urgent in recent years, and the key for achieving the outstanding performance is the suitable structural designing of active materials. Nanoarray architecture emerged as one of the most promising structures, as it can offer many advantages to boost the electrochemical performance. Specifically, this kind of integrated electrodes can provide a large electrochemically active surface area, faster electron transport and electrolyte ion diffusion, leading to substantially improved capacitive, rate and cycling performances. In this paper, we will review the recent advances in strategies for synthesis of materials with nanoarray architectures and their applications in supercapacitors and batteries.
