Isothermal charging/discharging experiment
Type of sample: Coin Cell LiR2032
IsothermalTests at controlled and constant temperature are called isothermal.Isothermal mode with temperature
set at 40°C
Constant current Constant voltage
(CC-CV) – 40 mA from 4.2 V to 3.0 V
The data shows that charging is characterized by a short endotherm followed by a small ExothermicA sample transition or a reaction is exothermic if heat is generated.exothermic reaction while discharging is characterized by a long exothermic reaction. Cycles are reliably repeatable.
The same data was used to calculate the cell efficiency during charging and discharging.
