RESEARCH

What is new in our project for global scientific research?  

The Polish – Norwegian group aim to develop CVD methods for controlled growth of  Mo2C, Ti2C and  V2C and Cr2C MXenes. Study their CVD growth mechanisms and understand atomistic processes during their application as anode material in solid state Li-ion battery.  All-solid- state Li-ion batteries are better compared to current Li-ion rechargeable batteries (LIBs) in the following aspects:

• chemically safer,
• compact,
• higher battery capacity,
• faster re-charging,
• operable at higher temperatures

Key novelty is to attempt to study in situ (in real-time) the atomic structure evolution in MXenes during Li-ions transport in them when used as an anode in a ASSB Li-ion battery.

Atomic structure model showing lithium ions transport between two monolayer sheets of molybdenum carbide (Mo₂C) Mxene material when used as the anode in a Li-ion battery (lithium ions -green, molybdenum atoms – blue and carbon atoms – black).

Through such studies fundamental insights into the atomistic structural factors in these materials that are responsible for their Li-ion loading capacity i.e. battery capacity can be understood. Such understanding will enable to inform for better design and development these materials to fully harness their Li-ion loading capacities.

Impact on daily life

With growing standards of living and increasing digitization of everyday life the global energy demands are also on rise. Re-chargeable Li-ion batteries are at the core of what powers the present-day internet of things (IoT) smart devices to develop new energy storage materials with higher energy storage capacities and safer for the environment is one of fundamental approaches to address this growing need of the human society. The current research efforts in the field of energy storage materials clearly show the impending progression towards ASSBs as the most likely next generation rechargeable batteries technology.
