Unordered vacancies engineered in host anode materials can't well maintain the uniform Na+ adsorbed and possibly render the local structural stress intense, resulting in electrode peeling and battery failure. Here, we firstly introduce the indium into Cu2Se to achieve the formation of CuInSe2. Next, ion extraction strategy is employed to fabricate Cu0.54In1.15Se2 enriched with ordered vacancies by the spontaneous formation of defect pairs. Such ordered defects, compared with unordered ones, can serve as myriad sodium ion micropumps evenly distributing in crystalline host to homogenize the adsorbed Na+ and the generated volumetric stress during the electrochemistry. Furthermore, Cu0.54In1.15Se2 is indeed proved by the calculations to exhibit smaller volumetric variation than the counterpart with unordered vacancies. Thanks to the distinct ordered vacancy structure, the material exhibits a highly reversible capacity of 428 mAh g−1 at 1 C and a high−rate stability of 311.7 mAh g−1 at 10 C after 5,000 cycles when employed as an anode material for SIBs. This work presents the promotive effect of ordered vacancies on the electrochemistry of SIBs and demonstrates the superiority to the unordered vacancies, which is expected to extend it to other metal−ion batteries, not limited to SIBs to achieve high capacity and cycling stability.This article is protected by copyright.

Cost‐effectiveness plays a decisive role in sustainable operating of rechargeable batteries. As such, the low cost‐consumption of sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs) provides a promising direction for “how do SIBs/PIBs replace Li‐ion batteries (LIBs) counterparts” based on their resource abundance and advanced electrochemical performance. To rationalize the SIBs/PIBs technologies as alternatives to LIBs from the unit energy cost perspective, this review gives the specific criteria for their energy density at possible electrode‐price grades and various battery‐longevity levels. The cost ($ kWh−1 cycle−1) advantage of SIBs/PIBs is ascertained by the cheap raw‐material compensation for the cycle performance deficiency and the energy density gap with LIBs. Furthermore, the cost comparison between SIBs and PIBs, especially on cost per kWh and per cycle, is also involved. This review explicitly manifests the practicability and cost‐effectiveness toward SIBs are superior to PIBs whose commercialization has so far been hindered by low energy density. Even so, the huge potential on sustainability of PIBs, to outperform SIBs, as the mainstream energy storage technology is revealed as long as PIBs achieve long cycle life or enhanced energy density, the related outlook of which is proceeded as the next development directions for commercial applications.
