BAT4EVER Autonomous Polymer based Self-Healing Components for high performant LIBs

Summary

Electrochemical reactions in battery materials normally lead to structural changes, which may cause degradation and damage, and thus causing the loss of functionality of the battery with cycling. Next-generation electrode materials for lithium-ion batteries are especially prone to these failure mechanisms because they react with greater amounts of lithium and thus undergo more drastic structural changes.
BAT4EVER refers to microscopic self-healing of the micro-damages generated during repetitive charging/discharging processes at the Silicon anodes, NMC-based cathodes and electrolytes aiming a significantly improved charge-discharge cycle and calendar life of the Li-ion batteries.
These challenging tasks will be overcome by applying self-healing polymer coverage around Si-NPs on the anode side and by synthesizing core-shell structured and thus redox-stabilised cathode nano-particles that are embedded in M-ions and H-bonds induced polymers. Ionogel and covalent bonded gels will initiate curing ability to the electrolytes.
These battery component development acts will be supported with extensive use of material and structure characterisation methods and with atomistic modelling and cell simulation efforts.
The processing technologies will be transferred to the scaling team of the consortium for prototype manufacturing. The prototypes will be tested under varies environmental and in next-generation cell phones as a case study.
