“…To improve the performance of ZIFs as anode materials for LIBs, we focus our attention on bimetallic ZIF to utilize the synergistic effect of two metal centers inspired by our previous work [16,[27][28][29]. To demonstrate the effectiveness of our bimetallic ZIF, we also synthesize the isostructural Zn-ZIF-8 and Co-ZIF-67 under a similar solvothermal approach by using 2-methylimidazole as the linker.…”

In this work, a bimetallic zeolitic imidazolate framework (ZIF) CoZn-ZIF was synthesized via a facile solvothermal approach and applied in lithium-ion batteries. The as-prepared CoZn-ZIF shows a high reversible capacity of 605.8 mA h g −1 at a current density of 100 mA g −1 , far beyond the performance of the corresponding monometallic Co-ZIF-67 and Zn-ZIF-8. Ex-situ synchrotron soft X-ray absorption spectroscopy, X-ray diffraction, and electron paramagnetic resonance techniques were employed to explore the Li-storage mechanism. The superior performance of CoZn-ZIF over Co-ZIF-67 and Zn-ZIF-8 could be mainly attributed to lithiation and delithiation of nitrogen atoms, accompanied by the breakage and recoordination of metal nitrogen bond. Morever, a few metal nitrogen bonds without recoordination will lead to the amorphization of CoZn-ZIF and the formation of few nitrogen radicals.

“…As important cathode candidates in LIBs, vanadium oxides and vanadate have attracted extensive interests owing to their abundant reservation, high specific capacity, and high Li + diffusion efficiency (Maingot et al, 1993; Torardi and Miao, 2002; Ng et al, 2007; Liu et al, 2009; Mai et al, 2010a,b; Wee et al, 2010; Liu and Yang, 2011; Pan et al, 2011a; Rui et al, 2011; Varadaraajan et al, 2011; Wang et al, 2011; Liang et al, 2013b; Jian et al, 2014; Zhou et al, 2014; Meng et al, 2016; An et al, 2017). For example, vanadium pentoxide (V 2 O 5 ) has a high theoretical capacity of 442 mA h g −1 , but its commercialization is still limited by poor cyclic stability (Owens et al, 1999; Cao et al, 2005; Wang et al, 2006).…”

Single crystalline fork-like potassium vanadate (K2V8O21) has been successfully prepared by electrospinning method with a subsequent annealing process. The as-obtained K2V8O21 forks show a unique layer-by-layer stacked structure. When used as cathode materials for lithium-ion batteries, the as-prepared fork-like materials exhibit high specific discharge capacity and excellent cyclic stability. High specific discharge capacities of 200.2 and 131.5 mA h g−1 can be delivered at the current densities of 50 and 500 mA g−1, respectively. Furthermore, the K2V8O21 electrode exhibits excellent long-term cycling stability which maintains a capacity of 108.3 mA h g−1 after 300 cycles at 500 mA g−1 with a fading rate of only 0.043% per cycle. The results demonstrate their potential applications in next-generation high-performance lithium-ion batteries.

Further, mPGM-MSCs disclosed robust mechanical flexibility with~96% of capacitance retention at a highly bending angle of 180°, and impressive parallel or serial interconnection for boosting capacitance or voltage output. As a consequence, our proposed strategy of filling the redox species into mesoporous graphene and other 2D nanosheets will open up new ways to manufacture high-compact and flexible energy storage devices ranging from supercapacitors to batteries.
