Накратко на български
Цинково-йонните батерии се изследват чрез използването на проводими метално-органични рамки за подобряване на анодите и катодите. Това помага за създаването на по-безопасна, екологична и евтина алтернатива на токсичните литиево-йонни батерии.

Teaming conductivity and chemical functionality in metal-organic frameworks for zinc‑ion batteries
The continuous depletion of fossil fuels and their connection to the rising atmospheric CO2 levels have aroused a severe global concern. Therefore, to mitigate these issues, the European Commission has set ambitious targets to make the EU climate-neutral by 2050. In line with this, the next generation of electrochemical energy storage (EES) devices with lower-cost, higher safety, sustainability, eco-friendliness, and performance is the need of an hour. In this direction, zinc-ion batteries (ZIBs) are proving to be an effective EES technology that could meet the future demand for green and safe storage of electric power, which is vital for a low-carbon and fossil-fuel-independent civilization. However, to exploit ZIBs for commercial applications and use them as an alternative to costly and toxic Lithium-ion batteries (LIBs) is very challenging. The commonly used cathodes for ZIBs such as manganese oxides, vanadium oxides, and Prussian blue. limit the rate capability of ZIBs because they severely suffer from decomposition and dissolution in the electrolyte. On the other hand, irregular stripping/plating in pristine Zn anode leads to the formation of Zn dendrites and short circuits, thereby reducing the cycle life of ZIBs severely. Therefore, the overall objectives of this work are to target the alternative anodes and cathodes for ZIBs to minimize the issues associated with the current state of the art based on highly porous and conductive metal-organic frameworks (CMOFs). The first objective is to find, optimize, synthesize, and characterize CMOFs that are suitable for depositing over pristine Zn anodes. The aim is to achieve uniform stripping/plating and minimize the Zn dendrites. The other objective is to select, optimize, synthesize, and characterize CMOF cathodes for ZIBs. The third objective is to synthesize and characterize the covalent interactions of CMOFs and graphene derivatives and use them as a cathode for ZIBs. The fourth objective is to use the optimized CMOF anode and cathode for the assembly of a full aqueous ZIB cell. In this objective, the anode of ZIB is also tested using synchrotron x-ray computed tomography (SXCT) to probe the dendrites and Zn dissolution in pristine and modified Zn anode during secondment in BAM, Berlin. Besides these four objectives, the other objective is planned to two-way transfer of knowledge between an experienced researcher (ER) and the host institute (HI), and also between ER and the secondment host. The final objective is to disseminate and communicate the project results from time to time. Hence, the Z-ION project is expected to offer indispensable knowledge for the advancement of low-cost, sustainable, and safer ZIB and will provide new avenues for EES technologies.

Цел на проекта
Zinc-ion batteries (ZIBs) are among the most promising electrochemical energy storage (EES) technologies that could meet the future demand for green and safe storage of electric power, which is vital for a low carbon and fossil-fuel independent civilization. However, the low cost, Earth-abundance and superior safety/stability of zinc (Zn) in comparison to lithium-ion batteries, comes with formidable challenges, such as slow zinc ion migration and dendrite growth, limiting their charging/discharging time and life-span. Recent advances have expanded the design toolbox of metal organic frameworks (MOFs) and of tailored graphene derivatives – the core expertise of the applicant and of the host institution, respectively– which could drive the developments towards the next generation of ZIBs. The Z-ION project comes to meet the fundamental need for decarbonisation enabling safe, sustainable and low-cost batteries via the exploration of 3D and 2D conductive MOFs (CMOFs) and hybrids thereof with tailored graphene derivatives as hosts for Zn, which have so far remained largely unexplored in ZIBs. The conductivity and open framework of these materials, in comparison to the present insulating and low porosity cathodes, can boost Zn ion migration. Functionalization of both materials with chemical groups suitable for Zn coordination can streamline a homogeneous and dendrite-free deposition of metallic Zn at the anode through directed nucleation in their frameworks and at coordination sites. Importantly, tailored graphene derivatives with dense out-of-plane functionalities can facilitate the formation of covalent hybrids with CMOFs, ascribing hierarchical porosity and conductive bridges between the CMOF particles or sheets. The Z-ION project will thus offer indispensable knowledge for the advancement of low-cost, sustainable, and safe ZIBs, which also offer one of the highest volumetric energy densities, necessary for storing a lot of energy in small-sized batteries.
