When charging or discharging a lithium-ion-battery (LIB), lithiation or delithiation of the electrodes takes place. Especially in the case of anode active materials, lithiation often leads to a significant volume increase. The latter can cause a rear

The Role of Silicon in Silicon-Graphite Composite Electrodes Regarding Specific Capacity, Cycle Stability, and Expansion

Autor: Erfan Moyassari, Thomas Roth, Simon Kücher, Chia-Chin Chang, Shang-Chieh Hou, Franz B. Spingler, Andreas Jossen

One promising way of compensating for the repeated volume expansion and contraction of silicon as an anode active material in lithium ion batteries (LIBs) is to embed silicon within a graphite matrix. Silicon-graphite (SiG) composites combine the adv

Publikováno v: ECS Meeting Abstracts. :421-421

Silicon-based electrodes are promising candidates to enable the next generation of Lithium-ion batteries with high energy densities on the cell level beyond 350 Wh kg−1 [1, 2]. Nevertheless, the commercialization of silicon-based electrodes is stil

Electrochemically Stable In Situ Dilatometry of NMC, NCA and Graphite Electrodes for Lithium-Ion Cells Compared to XRD Measurements

Autor: Franz B. Spingler, Simon Kücher, Andreas Jossen, Erfan Moyassari, Robert Phillips

Virtually all types of electrodes used in lithium-ion batteries expand and contract during cycling, which poses an engineering and design challenge. Information provided by X-ray diffraction (XRD) about alterations in the crystal structure of active
