Mastering Electrode Surface to Achieve Ultra-High Reversible Capacity
The MASTER aims to advance a new concept for the surface design of electrode materials to achieve reversible capacities that approach the theoretical ones. The consortium comprises multidisciplinary teams from Bulgaria, Spain and Turkey and it covers the full value chain from TRL2 to TRL4. The specific objectives are: (i) to understand the reactions at the electrode surfaces that currently prevent achieving the theoretical capacity; (ii) to exploit this knowledge to facilitate the elaboration of high-performance electrodes; (iii) to integrate the surface-modified electrodes into a full Na-ion battery; (iv) to maximize the impact of the project beyond the Na-ion batteries.
In this proposal, we aim to study next-generation cathode and anode active materials for Li-ion batteries which can be used in electric vehicles and consumer electronics. Li-rich and Ni rich layered- layered cathode active materials known as Li2MnO3-LiMO2 nomenclature and Si based composite anode active materials will be investigated as cathode and anode materials, respectively. Conventional synthesis methods such as solid state and combustion techniques will be employed to optimize the stochiometric ratio which will be supported by electrochemical performances. In addition, 3D unconventional current collectors will be explored to enhance the energy density of the next generation-based Li-ion cells by increase the areal loading of the cathode and anode materials. In addition to the common characterizations tools such as XRD, SEM, advanced characterization methods such as convergent beam electron diffraction (CBED) and selected area electron diffraction (SAED) will be studied. Along with a promising cycle life, it is the ultimate aim of this proposal to achieve 800Wh/L energy density with a fast charging capability that can provide 80% state of charge in 20 minutes. Along with next generation battery materials and novel 3D architectural designs what this proposal offers, we also believe our research-maturation and adoption methodology will expedite the data driven outcome of Li-ion cells.
The aim of the project is to develop a three-dimensional current collector for lithium metal batteries. The project also aims to increase the cycle life of lithium metal batteries and prevent the irregular growth of lithium on the current collector during cycling.
