Abstract:

Lithium-ion batteries in hand-held devices and laptop computer are a key part of our everyday lives. Looking into the future, these unique devices are also poised to become part of our general energy landscape, with increasing usage in storage of renewable but intermittent energy from wind and solar sources. Especially exciting is the development of batteries for transportation as it offers a much improved air quality in highly populated areas. However, charging times is still a challenge. For R&D this translates into a requirement of improved power performance.

In this talk we will explore the processes required to charge lithium-ion batteries, both from a theoretical and practical point of view. Specifically, we will focus on new techniques recently developed in our laboratory to characterize these processes. A central part of this work is to develop the in situ methods so that kinetic and power parameters can be extracted. In the final part of the talk, we will shift gears from characterization to material development i.e. all-organic electrodes recent developments, challenges and opportunities.
