Performance-limiting electrochemical reactions in lithium-based batteries
Despite the frequent use of lithium-based batteries there are still unanswered questions relating to their loss of performance during use. This affects the energy and power densities as well as the battery lifetime, all of which are essential in most applications (e.g., electric vehicles and large-scale electric energy storage).
Our research focuses on the development of a significantly improved electrochemical understanding of the performance-limiting effects to enable the development of lithium-based batteries with significantly improved performances. Our electrochemical results, show that these effects cannot be fully explained by contemporary models and that additional phenomena must be considered. More importantly, the results indicate that it is possible to extend the lifetime of the batteries significantly and that it may be possible to regenerate failed batteries. The scientific and practical implications of our findings are therefore considerable.
