Technical Data: Lithium-ion Battery LIB-12

We estimate the lifespan of lithium-ion batteries for the next 10 years based on storage test data.

AKTS Corporation's Thermokinetics can predict lifespan from accelerated test data using reaction kinetics and the Akaike Information Criterion. The storage test for lithium-ion batteries is also an accelerated test, estimating the capacity retention rate 10 years into the future from data on battery capacity retention rates. Instead of estimating lifespan using conventional methods, we calculate the degradation reaction model and its activation energy from the obtained measurement data. From the obtained reaction kinetics parameters, we can derive capacity retention rate curves for various time and temperature environments. 【Features】 ■ Temperature levels: 3 examples: 20, 40, 55°C; capacity retention rate data can estimate the capacity retention rate 10 years into the future from 30 to 40 measurement data points. ■ The estimated capacity retention rate curve is provided with a 95% prediction interval using the bootstrap method. ■ The degradation reaction equation and activation energy can be determined. *For more details, please refer to the PDF document or feel free to contact us.
