Microcalorimetry Improves Lithium-Ion Battery Testing
Researchers are utilizing isothermal microcalorimetry (IMC) to analyze heat transport and parasitic reactions in lithium-ion batteries. This diagnostic method allows for faster prediction of battery longevity and performance compared to traditional long-term cycling tests.
Why it matters
Improving battery testing efficiency is critical for accelerating the development of high-performance energy storage solutions for electric vehicles and consumer electronics.

Legacy approaches for cycling a cell to failure previously took many months; new diagnostic techniques can predict long-term behavior in a couple of weeks. One developing diagnostic method is to measure a battery's parasitic heat during cycling.
Krause et al. (2012) described a method for separating parasitic heat events from total heat generation, and thereby quantifying parasitic processes. 1 Parasitic response information can then be used to:
The following research examples use the TA Instruments TAM (Thermally Activity Monitor) microcalorimeter to assess battery parasitic reactions to new materials, formulations, and processing processes.
