High Throughput Development of Battery Materials: Gas Reduction Solutions

摘要

Gas evolution is a common problem for lithium-ion batteries, leading to reduced cycle life and cell failure. It has been especially problematic as cell makers and material suppliers strive to find solutions enabling cells to function at increased voltages in the quest for greater energy. Unfortunately, gas evolution can be difficult to detect in early development as it is masked by many other variables. Wildcat's in-situ gas measurements overcome these challenges, allowing for precise detection of gassing directly in the cell. The technique is able to monitor gas generation during the initial formation cycle and also in subsequent cycles. Wildcat measurements are real time and non-destructive to the electrochemical performance of the cell. Therefore, gas monitoring for a single cell can now be performed over the lifetime of that cell offering scientists new valuable insight. This poster will discuss the development of electrolyte formulations for high voltage applications with reduced gas generation.
