When engineering a new lithium ion cell, different battery components must be analyzed together to determine the chemical compatibility and likelihood for thermal decomposition. Proper measurement of reaction rates and thermodynamics is improved by running larger samples sizes in cases such as these where there are multiple phases reacting.
The following graphs depicts the reactions between different electrolytes and a custom anode material. These adiabatic tests, available from the ARC® 244/254, or the MMC 274 Nexus®, show the variety of different reactions that can occur. The onset of the reaction is an important criteria but so is the relative sizes of the reaction rates in determining which combinations will lead to a safer battery.
