In situ electrochemical atomic force microscopy studies of a copper surface during lithium plating and dissolution — •Luca Kaufer1, Ronja Haas2, Thomas Göddenhennrich1, Daniel Ebeling1, Jürgen Janek2, and André Schirmeisen1 — 1Institute of Applied Physics, Justus-Liebig-University, Gießen, Germany — 2Institute of Physical Chemistry, Justus-Liebig-University, Gießen, Germany
The increasing concern about climate change and the transition to sustainable energy sources has led to a increased demand for high energy density batteries for energy storage. Lithium is considered a favourable anode material[1]. However, challenges like dendrite growth when used in batteries are still present[2]. This investigation focuses on the processes involved in dendrite formation and growth and upcoming side reactions in a lithium-copper system with in situ electrochemical atomic force microscopy as a method. We will cover two topics. Firstly, the technical development of an appropriate measurement setup for in situ investigation of cells in atomic force microscopy. Secondly, the presentation of initial findings on the processes of formation and growth of dendrites within a lithium-copper cell system.
