Abstract:

As a significant intermittent supporter, traditional rocking-chair batteries [lithium-ion batteries (LIBs)] have been widely used in consumer electronics, electric vehicles, and energy storage power stations owing to their long-term cycle life and absence of the memory effect. However, owing to the shortage and uneven global distribution of lithium and cobalt resources and the growing unprecedented demand for power batteries in electric vehicles and grid-scale energy storage stations, it is essential to develop novel energy storage technologies that are efficient, low-cost, safe, and reliable, for example, secondary batteries based on non-lithium cations (e.g., Na+, K+, Mg2+, Ca2+, Zn2+, and Al3+), zinc-air batteries, and dual-ion batteries (DIBs). Among them, DIBs are emerging energy-storage systems, which are different from traditional LIBs, in that both cations and anions participate in the electrochemical redox reactions of the anode and cathode, respectively. This feature endows these novel energy-storage systems with more options for electrode materials and the advantages of a high working voltage, wide working temperature range, optimum safety, low cost, and environment friendliness; therefore, these novel energy-storage systems show considerable application prospects in large-scale energy storage applications. Herein, we first present the development history of DIBs. Furthermore, on the basis of the working principle of DIBs, we systematically reviewed state-of-the-art materials and identify the challenges of using them in DIBs.
