“…COFs have picked up intense attention of researchers worldwide due to their promising applications in heterogeneous catalysis (Ding and Wang, 2013, Tu et al., 2018, Yan et al., 2018), energy storage (Cao et al., 2019, Xiao and Xu, 2018, Zhang et al., 2017b, Zheng et al., 2019, Zhou and Wang, 2017), analytical chemistry (Qian et al., 2018b, Zhang et al., 2018d, Zhang et al., 2019), and light conversion (Banerjee et al., 2018). As an emerging class of organic crystalline materials, COFs offered some specific advantages not found in other types of materials: modularity, porosity, stability, and metal free (Chandra et al., 2013, Kandambeth et al., 2012).…”

“…Another existing issue for zinc-based battery is the dendritic Zn deposition, which potentially triggers an internal short circuit ( Li et al., 2018a , 2018b ; Yuan et al., 2018 ). These challenges are alleviated with the multiple approaches of a standard Zn-Br 2 flow battery: (1) Bromine complexing agents transform the soluble Br 3 - species to oily phase ( Winsberg et al., 2017 ; Wu et al., 2019 ); (2) storage of the oily phase in separated reservoirs allows bromine convection and improves the limiting current density for Zn deposition ( Gur, 2018 ; Soloveichik, 2015 ); (3) ion-selective membrane further prevents cross-diffusion and short circuits ( Hu et al., 2017 ; Zhang et al., 2019 ). These approaches are compromised at the expense of cell resistance, energy efficiency (normally <80%), and increased system size and complexity ( Biswas et al., 2017 ; Zhao et al., 2015 ).…”

Summary The highly reversible zinc-bromine redox couple has been successfully applied in the zinc-bromine flow batteries; however, non-electroactive pump/pipe/reservoir parts and ion-selective membranes are essential to suppress the bromine diffusion. This work demonstrates a zinc-bromine static (non-flow) battery without these auxiliary parts and utilizing glass fiber separator, which overcomes the high self-discharge rate and low energy efficiency while the advantages of the zinc-bromine chemistry are well preserved. It is achieved by a multifunctional additive, tetrapropylammonium bromide (TPABr), which not only mitigates the bromine cross-diffusion by regulating the fluidic bromine to a condensed solid phase but also provides a favorable interface for zinc electrodeposition toward non-dendritic growth. The proposed zinc-bromine static battery demonstrates a high specific energy of 142 Wh kg −1 with a high energy efficiency up to 94%. By optimizing the porous electrode architecture, the battery shows an ultra-stable cycling life for over 11,000 cycles with controlled self-discharge rate.

“…applications. [18][19][20][21][22] The interaction exerted by the guest with the adsorption site perturbs the local environment of the host, leading to its instantaneous structural adaptation. This usually does not undermine the integrity of the guest, since its relative free motion allowed within the pore does not constrain the structural adaptation to its new states.…”

The assessment of the architectural stability of molecular porous materials is not yet a common practice, but critical to their understanding and development. The conformational adaptation of porous materials to guest binding and other chemical dynamics poses a risk of architectural damage, leading to performance deterioration during their prolonged usage. The deformation of the framework backbone and the disconnection of building units are driven by chemical, mechanical, and thermal perturbations, and can be quantitatively described by the term connection completeness. Analytical means that can be used to measure this parameter are presented in order to provide a standard, practical protocol for evaluating architectural damage made to framework materials. Preventive and remedial strategies are proposed for enhancing the architectural integrity of frameworks without compromising their functional mechanisms, paving the way to the design of robust yet adaptive materials. In this way, the discussion on architectural stability is initiated, and readers are encouraged to carefully characterize molecular porous materials for a better understanding of their structure-property relationship.
