[Technical Data] Heat Generation Characteristics of the Crystallization Process of Substances LIB-06

Technical documentation on the exothermic characteristics of the crystallization process of substances filled in laminate film.

This document includes measurement examples using LIBCAL_A5 (calorimeter) to measure the heat generation and absorption of A5 size lithium-ion batteries. We measured the heat generation reaction of ECO heat packs, which contain heat-generating substances like laminated lithium-ion batteries, packed in polymer film. Instead of deforming a piece of iron to start crystallization, we introduced seed crystals to initiate the crystallization after setting it in the heat flow detection module. [Contents (excerpt)] ■Fig-01: Heat generation curve of ECO heat pack ■Fig-02: Raw data heat flow curve and temperature curve at 3 minutes and 40 seconds after crystallization began ■Fig-03: Heat flow curve and temperature curve with time constant correction for 14 minutes after crystallization began ■Fig-04: Heat flow curve and temperature curve for 4.5 hours after crystallization began, etc. *For more details, please refer to the PDF document or feel free to contact us.
