Battery Material Testing and Validation
Chem4Batteries is conducting a project on battery material testing and validation for automotive lithium-ion batteries. The work includes testing electrolytes with various cathode and anode setups to support advanced automotive uses.
The project focuses on testing and validating non-flammable, high-conductivity electrolytes with strong electrochemical stability. A central component of this project work involves the evaluation of these new electrolytes in conjunction with manganese-rich cathodes (LNMO), lithium manganese iron phosphates (LMFP), and lithium-rich layered oxides (LMR), in combination with graphite and silicon-based anodes. The validation process adheres to stringent OEM standards for pouch cells and 21700 cylindrical cells, encompassing parameters such as nominal capacity, specific energy density, and rate capability. Notably, the advanced electrolyte has resulted in a significant decrease in energy release during thermal runaway events, thereby enhancing thermal safety.
At the outset of the project, a thorough screening of materials is carried out, followed by advanced electrochemical analysis and evaluation of battery materials. The process also includes long-term cycling tests on both laboratory and prototype cells, using pouch and cylindrical battery cell formats.
In laboratory-scale experiments, the Chem4Batteries team employs pouch cells in either single- or multi-layer configurations, leveraging previous experience with assembling 21700 cylindrical cells and conducting detailed battery material testing and validation.
Chem4Batteries advanced automotive battery technology by testing battery materials that optimize energy density, safety, and sustainability. This project demonstrates our commitment to technical excellence and battery innovation.
