Zeolitic imidazolate framework derivatives as anode materials for sodium and potassium-ion batteries: a mini review

“…Liang et al prepared Co/CoSe nanocrystalline heterojunction hollow carbon nanospheres, which improved the electron cloud distribution of the material. 163 These composites exhibited high capacity, delivering 461.9 mA h g −1 after 200 cycles at 1 A g −1 and 145.9 mA h g −1 after 3000 cycles at an ultra-high current density of 10 A g −1 . Table 4 consolidates the electrochemical performance of ZIF-derived TMSes as anode materials in recent research.…”

ZIF-derived TMPs in PIBs Furthermore, several research groups have demonstrated that TMPs are highly effective in PIBs due to their substantial theoretical capacities and lower polarization potentials.…”

Intrinsic carbon structure modification overcomes the challenge of potassium bond chemistry

“…Various modification strategies involving microstructure regulation, heterostructure design and confinement space construction, etc., have been applied to accommodate the volume effect of carbon anodes during the potassium storage process. [112][113][114] Recently, it was shown that the heteroatom-doped carbon materials with expanded interlayer distance can accommodate foreign ion storage and alleviate the volume expansion effect. Wen et al 115 fabricated S/N co-doped carbon nanosheets (S-N-PCNs) as the PIB anode, and non-doped and single-doped samples (PCNs and N-PCNs) were also prepared for comparisons.…”

SnO2/Sn with core–shell structure Schottky heterojunctions loaded in graphene to promote electrochemical reaction kinetics and enable efficient lithium-ion storage

“…The SnO 2 /Sn Schottky heterojunctions were originally constructed to ensure close contact and electronic coupling between SnO 2 and Sn crystal surfaces, which facilitates the reduction of ion adsorption energy at the heterointerfaces. 25 To determine the successful preparation of the Schottky-type SnO 2 /Sn nanorods heterostructures during the experiments, TEM was used to characterize the morphology and structure of SnO 2 /Sn/G samples. As shown in Fig.…”
