Using redox agents to enhance the performance of lithium-air batteries and lithium recycling — •Nuria Garcia-Araez — University of Southampton

Lithium-air batteries can become the next generation of battery technologies, since they can potentially deliver 5 times more energy than current lithium-ion batteries of the same weight, while having a lower cost and being more environmentally friendly. Unfortunately, the performance of the current lithium-air batteries is limited by three fundamental issues: electrode passivation, degradation reactions and poor kinetics of the desired reactions. Luckily, this talk will show that all these issues can be solved by incorporating suitable redox agents, which can act as shuttles and mediators. As the performance of lithium batteries improves, and the global population increases, the demand for lithium can only increase in the future, and therefore lithium recycling and recovery will need to be developed. This talk will also present a new method for lithium recycling that is based on the combination of redox agents and battery materials.
