Accelerating Battery Research and Development with In-operando Isothermal Microcalorimetry

The electrochemical processes that take place in batteries, whether under load or at rest, give rise to heat exchange with the surroundings. These processes include redox reactions at the anode and cathode, the shuttling of lithium ions between electrodes, and the various parasitic side reactions that are responsible for limiting the lifetime of a battery.

Screening new cell chemistries using traditional electrochemical methods is a time-prohibitive process that significantly slows the pace of research. These methods involve cycling the cell until signs of degradation or sufficient capacity fade are evident, and typically take months to complete. In-operando isothermal microcalorimetry is an established but underutilized technique for measuring the activity of parasitic, or non-reversible reactions during charge cycling to provide insights for accelerating battery research.

This webinar will give an overview of In-operando isothermal microcalorimetry and the integrated Battery Cycler Microcalorimeter Solution, an essential tool for increasing the pace of research and illuminating new insights of battery chemistry.
