Development of tomorrow's lithium-ion batteries
With the aim of making composite anodes for lithium-ion batteries more stable and more efficient, Christopher Rojas wrote and successfully defended a master's thesis on the topic "Chemomechanical study of silicon composite anodes for lithium-ion batteries" at the Group of Electrochemistry and Electroplating at TU Ilmenau.
In his investigations, the master's student relied on silicon in combination with MXenes, i.e. two-dimensional inorganic compounds. With this approach, he has succeeded in producing a more conductive electrode material with reduced aging during charging and discharging. "He is thus making significant contributions to the development of tomorrow's lithium-ion batteries," said his supervisors on the occasion of his defense.
With the completion of his thesis, Christopher Rojas has at the same time taken the last hurdle on his way to the international double degree of the master's programme in materials science of the Pontificia Universidad Católica del Perú and the TU Ilmenau.
The thesis was written at the Group of Electrochemistry and Electroplating, which, under the direction of Prof. Andreas Bund, deals with fundamental and applied issues in electrochemistry and electroplating such as ionic liquids, electrochemical surface engineering and corrosion, electrochemical energy storage and conversion, photoelectrochemistry and conductive polymers.
