Anode Compatibility with Different Electrolytes
When engineering a new lithium ion cell, different battery components must be analyzed together to determine the chemical compatibility and likelihood for thermal Réaction de DécompositionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. 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 AdiabatiqueAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC®). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.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 criterion but so are the reaction rates in determining which combinations will lead to a safer battery.
