“…Practical applications of metal sulfides are hampered by two major challenges: slow kinetics due to the inherently low conductivity of metal sulfides, and limited cyclability due to severe volume expansion during charge and discharge. 555–559 To address these drawbacks, several strategies have been proposed, including morphology engineering and heterostructure engineering. 343,347,349,393–399,559–563 Morphological engineering includes the design of core–shell structures, porous structures, hollow structures, and refinement of active particles, which can effectively mitigate the volume fluctuations during potassiation/depotassiation.…”

Iron carbodiimide (FeNCN) often suffers from unstable interfacial structure with an unexpected failure of Na-ion storage performance. In this work, Co 3 O 4 particles were deposited on the surface of FeNCN. This Co 3 O 4 nanolayer led to the formation of a Na 2 CO 3 -rich inorganic component SEI film to enhance the stability of a promoted-loading FeNCN electrode interface with fast Na + migration pathway. Benefitting from this strategy, the FeNCN electrode could present a capacity retention rate of 99.95% per cycle after 1500 cycles at 1 A g −1 . The design of interfacial structure in a promoted-loading electrode could be a reference for stable and high-rate performance of carbodiimide-based materials.

Potassium-ion batteries (PIBs) are highly attractive and are promising energy storage technology because of their cost-effectiveness, superior safety, environmental friendliness, as well as high standard K/K + redox potential, and abundance and low cost of potassium. Transition metal disulfides (TMDs) have a wide interlayer spacing that is attractive as a K + storage site in PIBs. Moreover, TMDs have high reversible capacity and are low cost. Nevertheless, they have not been extensively studied. The practical application of TMDs is impeded by their fast capacity fading and poor rate performance. More well-focused research should aim for the commercialization of TMDs in PIBs. This paper reviews (a) the main strategies to enhance the application of TMDs in PIBs; (b) the recent development of using TMDs such as MoS 2 , WS 2 , and SnS 2 as electrode materials for PIBs, including their structure, performance, and defects, as well as the methods to alleviate their defects; (c) the associated electrochemical processes; and (d) the critical issues, challenges, and prospects.
